Respuesta :
-12(x+5)=144
(use distributive property) -12x+ (-60)=144
+60 +60
-12x=204
-204 -204
-12x-204=0
+12x +12x
-204=12x
-204/12 12x/12
-17=x
x=-17

First you have to distribute the -12 to the x and 5. So you would get -12x -60=144. Then you add 60 to each side and get -12x=204. Then divide 204 by -12 and you get the answer of x=-17.
