144=-12(x+5)
Divide thru by 12
12 = -(x+5)
Divide by -1
-12 = x+5
Subtract 5
x = -17

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
