Solve for x.

6(x – 1) = 9(x + 2)

x = –8
x = –3
x = 3
x = 8

So first multiply:
6x -6 = 9x + 18
then we "move the numbers ":
6x-9x= 18 +6
the positive and negative signs will change. anyways, now combine the like terms:
-3x= 24
now we divide 3 from both sides in order to isolate x:
-3÷3x= 24÷3
-x = 8
noq divide the negative from both sides:
x= -8

6(x – 1) = 9(x + 2)
6x - 6 = 9x + 18

9x - 6x = -6 - 18
3x = -24
x = -24/3
x = -8

In short, Your Answer would be -8 [ Option A ]

Hope this helps!

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"
