Step-by-step explanation:

All you have to basically do on this one is go backwards.

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).


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


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
