-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
