5x+ 20 = 3x +66
-3x -3x
2x+20=66
-20 -20
2x=46

X=23

First we need to combine like terms. so we move the like terms to different parts of the equation:
5x -3x = 66-20
then we combine the like terms:
2x= 46
bow we divide both sides by 2 to isolate x:
2x ÷2= 46 ÷2
x= 23
any questions? just ask. I hope this helped! :)

Georgia [21]
