Answer: x = -3
Step-by-step explanation:
Let’s use the distributive property
-12(x-12) = -9(1+7x)
-12x+144= -9-63x
Then let’s get all the numbers and variables on each side
51x= -153
Next let’s divide each side by 51
X=-3
Finally let’s check our answer by substituting ‘x’ for -3
-12(-3 -12)= -9(1 +7(-3))
36+144= -9 + 189
180 = 180
So ‘x = -3’ is the correct answer
