If you encounter an equation with variables on both sides, the here's what you need to consider. 1) If you have to, use the distributive law/property. 2) After that, you need to combine like terms. 3)Then, try to get the variable on one side of the equal sign. 4)Try to get constants to the other side. 5) Finally, you need to solve for x. I hope this answers your question! :)
Here's an EASY example...
Ex. 3x + 2 = 2x + 5
- 2 = - 2
3x = 2x + 3
- 2x = -2x
x = 3
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
You try to bring all instances of the variable to one side. Here is an example:5x + 5 = 3x - 2 Subtracting 3x on both sides: 2x + 5 = -2 Subtracting 5 on both sides: 2x = -7
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
The variables may have different values.
-85-6x=91+2x
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
7X + 2 = 5X - 1 subtract 5X from both sides 2X + 2 = -1 ==============
combining like terms or subtracting from both sides of the equation.
If an equation has two variables, we'll call them (x,y), the variables can be any value as long as both sides of the equation have the same result. If the equation was x = y, then the variables could be (1,1), (2,2), (3,3),etc...
1) distribute 2) combine like terms 3) get all variables on one side 4) get contsants to the other side 5) find x
They have to be across from each otherJoin the equationsSolveYou will know if you got it right if your slope is the same for both sides
