4x-7+7=2x+3+7

Balancing Equations

Step by Step How-to (Click for a link to a video!)

4x-7+7=2x+3+7Add the numbers without an 'x' attached

4x - 7 = 2x+3 +7 +7 Add 7 to both sides first

4x-7=2x+3

4x = 2x + 10 -2x -2xGet all of the x'es on one side of the equals sign

4x-2x=2x-2x+10Add the numbers with x attached

2x=10 2 2Divide both sides by 2 to isolate x (make 'x' be the only thing on one side of the equals sign)

Combine like terms

4x-7=2x+3

4x=2x+10

4x-2x=2x-2x+10
