Question 230828
144 = -12 * (x + 5)


Remove the parentheses by multiplying each term within the parentheses by -12 to get:


144 = (-12 * x) + (-12 * 5)


Simplify this by multiplying out the terms and combining like terms to get:


144 = -12*x - 60


add 60 to both sides of this equation to get:


144 + 60 = -12*x


combine like terms to get:


204 = -12*x


divide both sides of this equation by (-12) to get:


204 / (-12) =  (-12) * x / (-12)


Simplify and combine like terms to get:


-17 = x


You have x = -17 as your answer.


replace this value for x in the original equation as shown below:


original equation is 144 = -12 * (x + 5)


replace x with -17 to get:


144 = -12 * (-17 + 5)


combine like terms within parentheses to get:


144 = -12 * (-12)


simplify and combine like terms to get:


144 = 144
