• Identity property of addition

Solving Equations with Variables on Both Sides

Ex. #1 : 

       5(x+2) = 3x-8

Make sure you follow these steps when facing an equation with variable on each side.

Multiple Choice

If my equation is 9y + 15 + 3y = 6y - 3 what would be the BEST first step?

• subtract 6y from 9y (9y-6y) to get all the variables on one side

• combine 9y and 3y (9y + 3y=12y) so that all the like terms on each side are together

• combine (-3 +15 = 12) to combine like terms
