How do you solve equations with like terms on one side of the equal sign?

You move one of the like terms to the other side using algebraic operations. For instance...
3x + 5y = 7x + 3
... and you want to solve for x ...
... first, subtract 3x from both sides ...
3x - 3x + 5y = 7x - 3x + 3
5y = 4x + 3
... do I need to explain further???

Sin x cos x equals 0?
For the product to be zero, any of the factors must be zero, so you solve, separately, the two equations: sin x = 0 and: cos x = 0 Like many trigonometric equations, this will have an infinity of solutions, since sine and cosine are periodic functions.
Is 4x and 4y like terms?
no,, to be like term they must have the same variable,, such as 4x and 9x.. or 1y and 300y...
4x -7x is this like terms or unlike terms?

What are the possible solutions for a system of equations?
The system of equations can have zero solutions, one solution, two solutions, any finite number of solutions, or an infinite number of solutions. If it is a system of LINEAR equations, then the only possibilities are zero solutions, one solution, and an infinite number of solutions. With linear equations, think of each equation describing a straight line. The solution to the system of equations will be where these lines intersect (a point). If they do not intersect at all (or maybe two of the lines intersect, and the third one doesn't) then there is no solution. If the equations describe the same line, then there will be infinite solutions (every point on the line satisfies both equations). If the system of equations came from a real world problem (like solving for currents or voltages in different parts of a circuit) then there should be a solution, if the equations were chosen properly.
Like terms have the same variable but may be raised to different powers?
No. Like terms should contain the same variable or variables, raised to the same powers. Like terms are those that can be combined by addition or subtraction.
How do you solve for x with equal values method?
First, if you have two equations like, for instance .90x+2000 and .40x+3500 then you would set them equal to each other like this ( .90x+2000=.40x+3500). Then you would solve for x by simplifying the equations as far down as you can.
How do you solve three nonlinear equations in three parameters?
There isn't a universal way to do this, just like there isn't a universal way to solve nonlinear equations in one variable. A good place to start, however, would be to attempt to solve an equation for one of the variables, in terms of the other two. If you substitute that into the other equations, you will then have a system of two equations in two variables. Do this again, and you'll have a single variable equation that you'll hopefully know how to solve.

What is x in the quadratic equation x2 plus 6x-18?
Sorry, that is not an equation, since you have not told us what those terms equal. An equation would look like this: x2 + 6x -18 = 0 (but it doesn't have to equal zero, that is just an example of what it might be). Until we have an actual equation, we cannot solve for x. Also note: you can go to the site wolframalpha.com and they can solve equations and graph them for you. Very convenient.
How do you simplify linear equations?
Start by collecting like terms...
Why was complex numbers dicovered?
To solve equations like x2+a=0 with a>0
What is the answer to this inequality 3p - 6 21?
The answer to the equation is p is equal to nine. You solve the equation by putting like terms together and then solving for p.
How do you solve equations that look like y over 6 plus 6 equals negative 8?
You substract 6 to -8 so its equal to y over 6 equal -2 and the you multiply -2 by 6! So the y equal -12...
What two numbers when added equal 6 and a half and when multiplied equal 64?
This problem actually has no solution. Any two numbers that will add to 6.5 will be too small to produce a multiple equal to 64. However, for problems like this in general, writing the question as a formula might help you solve it. 1. Assume the numbers are x and y. 2. Write two equations (two unknowns and two equations gives you enough information to solve). -The first part, "two numbers added equal 6.5" can be written as x + y = 6.5 -The second part, "two numbers multiplies equal 64" as xy = 64 3. Manipulate the equations to solve. For example: y = 64/x x + y = x + (64/x) = 6.5 4. Solve for x, and then use x to find y using either of the original formulas.
What are the steps to solving equations?
combine like terms order of operations () 2 X / + - and that's it.
What are joint variation equations?
Joint variation equations are equations that have a variable equal to the product of two or more other variables and usually a coefficient. For example, an equation like x=2yz.
How do you solve algebraically the system of equations?
You can solve a system of equations using a few methods: elemination and subsitution. In the elemination method you would multiply each of your equations by a factor that would cause one of the variables to be eleminated. ex: If you had 2x-3y=5 and 3x+6y=4 you would multiply the first equation by a factor of 2 (distributing the 2 to each term), giving you a new equation of 4x-6y=10. Now your y terms would cancel. You line up the equations like: 3x+6y=4 4x-6y=10 you simply cancel the y terms and add the others giving you: 7x=14 you then solve for x (in this case divide by 7) x=2 now you plug in x=2 into one of the first equations and solve 3x+6y=4 3(2)+6y=4 plug in x 6+6y=4 multiply 6y=-2 add like terms y=-1/3 solve for y To solve using the subsitution method you would take an equation and solve for one variable then plug that into the other equation. ex. (using the same equations as before) 2x-3y=5 2x=3y+5 x=(3/2)y+(5/2) 3x+6y=4 3((3/2)y+(5/2))+6y=4 plug in for x (9/2)y+(15/2)+6y=4 distribute the 3 (21/2)y=(-7/2) add like terms y=(-1/3) solve for y you would then plug in y and solve for x 2x-3(-1/3)=5 2x+1=5 2x=4 x=2 Hope this helps!
