A two step equation that equals 5?
2x+2=12
Explain the difference between the directions solve evaluate and simplify?
To solve would be to rewrite the equation in terms of the variable in the equation. For example, solve: 3x-2=7. You would solve for the variable x; e.g. 3x=9 and x=3. To evaluate, you would be given an equation with a variable or variables. You would need to be given a value for the variable(s) to substitute into the equation. For example evaluate the equation for x=3; equation is x2+1. Substitute 3 in for x; or 32+1=10. To simplify, reduce the equation to its simplest form. This will involve operations such as: factoring, adding, subtracting, dividing, canceling terms, and so forth. For example simplify the equation: 3x3/9x2. The 3/9 is simplified to 1/3 and x3/x2 is simplified to x. So the original equation simplified is: 1/3 times x or (1/3)x or x/3.Which is the right answer for most of you who does not know.
What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
How do you do a 2 step equation?
When you are solving a 2-step equation, you do the opposite of a 1-step equation. You do addition and subtraction first, then the multiplication second. Example: 2x + 9=16 -9 -9 2x=7 Now it's a 1-step equation 2x=7 /2 /2 Your answer would be 3.5 To check all you do is replace the variable with your answer. 2x + 9=16 2(3.5) + 9=16
How do you solve systems by using the substitution method?
You solve one of the equation for one of the variables. For example, if the variables involved are "x" and "y", you might solve for "y". It doesn't really matter what variable you solve for first, so you can solve for whatever variable is easiest to solve. Then - assuming you got, for example, "y = 3x -1", in this example you would replace every "y" by "3x - 1" in the other equation or equations.
How can you find equation of the line passing thruogh two points?
. the equation of a straight line can be found by using two points on a line . First find the gradient of the line using the gradient formula . now substitute the gradient into general form replacing "m" . use one of the points and substitute into equation to solve "c" example 1: find the equation of the line which passes through the points (1,3) and (2,5). step 1: find the gradient M=5-3/2-1=2 (/=divide) step 2: place m into the equation Y=2x+c step 3: substitute point into equation 3=2(1)+c step 4: solve C=1 equation is Y=2x+1 hope that helps :)

How do you solve log sub 9 parenthesis a over 27 closed parenthesis equals x minus 2?
Your equation has two variables in it ... 'a' and 'x'. So the solution is a four-step process: 1). Get another independent equation that relates the same two variables. 2). Solve one of the equations for one of the variables. 3). Substitute that into the other equation, yielding an equation in a single variable. Solve that one for the single variable. 4). Substitute that value back into the first equation, and solve it for the second variable.
How do you solve 1- 2cos squared theta without a calculator?
-1
How does factoring help solve quadratic equations?
Well, that's one method to solve the quadratic equation. Here is an example (using the symbol "^" for power): solve x^2 - 5x + 6 = 0 Step 1: Convert the equation to a form in which the right side is equal to zero. (Already done in this example.) Step 2: Factor the left side. In this case, (x - 3) (x - 2) = 0 Step 3: Use the fact that if a product is zero, at least one of its factors must be zero. This lets you convert the equation to two equations; x - 3 = 0 OR x - 2 = 0 Step 4: Solve each of the two equations.
How do you substitute y equals 4 into the equation x plus y equals 5?
y=4 x+y=5 so it wud be:::::: x+4=5 solve it from there by doing 1 step equation :)

What is the graph for x plus y equals 1 Need a step by step explanation?
The line x + y = 1 will be defined by the points that satisfy that equation. The x-axis travels horizontally, the y-axis travels vertically. Step 1. Draw the axes on graph paper. Each line should be an integer. Step 2. Plot points that satisfy the equation, like (0,1)(1,0)(2,-1)(1,-2)(3,-2)(-2,3) Step 3. Draw a line through them with a pencil using a straight edge of some sort. When one of the numbers is zero, that's where it crosses the other axis. You'll find that the line crosses the x-axis at 1 on the y-axis and crosses the y-axis at 1 on the x-axis.
