Start by distributing:
-12(x+5) = (-12 * x) + (-12 * 5) = -12x - 60
144 = -12x - 60
Add 60 to both sides to start isolating your variable:
204 = -12x
Solve for x by dividing both sides by -12:
x = -17
Step-by-step explanation:
multiply -12 with x and 5, after you get the answer. subtract 60 on the left and right, after getting 84 divide it by -12 and the final answer will be -7
