How Do You Solve 144=-12(x+5)?

Joseph Burton answered

First you would divide each side by -12
-12=x+5
then you would minus 5 to each side
-17=x
that leaves you with the answer that x is -17.

144=-12(x+5),144=-12x+-60,-12x=144+60,-12x=204,x=-204/12=-17.So the answer is -17.

Clear bracket
144=-12x-60
add -60 to both side.
-60+144=-12x-60+60.
84=-12x.
Divide both side by -12.
X=-7
