if anyone answers this is a BEAST !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 Step 1: -24x – 12 + 24x = -72x + 132 Step 2: –12 = -72x + 132 Step 3: -144 = -72x Step 4: 2 = x

Remark

I'm just going to give you a very brief answer.

Step One: The distributive property to remove the brackets.

Step Two: You are collecting like terms on the left. It's the additive inverse property of 0 for the two  "24x"s Some people think it's the distributive property as well.

Step Three: The additive inverse of 132 is added to both sides.

Step Four: Multiplication by the multiplicative inverse of -72 (1/ -  72)
