The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).

12-4=8

Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.

8/4=2

Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12

Hope this helped!
