Question

HELP!!!! Justify each step of the solution by stating the property that was used to get to each step. Given: 4(-6x – 3) + 24x = -72x + 132 -24x – 12 + 24x = -72x + 132 Step 2: –12 = -72x + 132 Step 3: -144 = -72x Step 4: 2 = x

Answer 1

First is the distributive property. then you add 24x to each side, giving you -12=96x+132.  You then subtract 132 from each side giving you -144=96x. To get the variable "x" by its self, you divide each side by 96 giving you x=-1.5
