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

-2x + 6 = 10x + 15

6 = 10x + 15 + 2

6 = 12x + 15

6 - 15 = 12x

-9 = 12x

-9/12 = x

-3/4 = x     or in decimal form; -0.75

hope this helps, God bless!

Ok so multiply the numbers out to get -2x+6=10x+15 Then add 2x to both sides getting you 12x+15=6. Then subtract 15 from both sides, leaving you with -9=12x. Then divide 12 from both sides, meaning x=-3/4
