solve -2(2x + 5) - 3 = -3(x - 1)

-4x - 10 -3 = -3x + 3
-4x - 13 = -3x + 3

Add 3x to both sides
-4x - 13 +3x = -3x +3

Simplify
-x - 13 = 3
Add 13 to both sides
-x - 13 + 13 = 3 + 13

Simplify
-x = 16

multiply both sides by (-1)
x = -16

-2(2x + 5) - 3 = -3(x - 1)...distribute thru the parenthesis
-4x - 10 - 3 = -3x + 3 ...simplify
-4x - 13 = -3x + 3...add 3x to both sides
-4x + 3x - 13 = 3 ...add 13 to both sides
-4x + 3x = 3 + 13 ...combine like terms
-x = 16 ... multiply by -1 to make x positive
x = -16
