Answer:
B
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).
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!
