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
