Question

Multi step variables I need a step by step or something

Answer 1

First distribute the 3 so you'll have:

12+12x=12x+12

Next you subtract 12 from both sides and you'll get:

12x=12x

then you divide both sides by 12 and you get:

x=x

Answer 2

Problem: 3(4+4x)=12x+12

The first thing that you need to do is distribute 3(4+4x).

12+12x=12x+12

Subtract 12x from both sides.

12=12

This means that the equation has infinitely many solutions.

I hope this helps you :)
