-3x + 15 =2x
15 = 2x+3x
15 = 5x
15/5 = x
3 = x

Multiply it out first:
-3X+15=2X then add 3X to both sides
15=5X Divide by 5 on both sides
X=3

Distribute, then simplify equation, by getting x on one side, and your number on the other.
-3x+15=2x
-5x+15=0
-5x=-15
x=3

-3(x-5)=2x
-3x + 15 = 2x (remove the parenthesis)
-3x - 2x = -15 (reorganize and collect terms)
-5x = -15 (simplify)
x = 3

distribute, -3x+15=2x
add 3x ..... 15=5x
divide 5
thus x=3

-3x + 15 = 2x
-3x - 2x = -15
-5x = -15
x = 3
Solution: {x belongs to R| x = 3}
