In solving a problem like this, the first thing we want to do is isolate the parentheses. To do this, we must subtract the "+12" from both sides.
(3xB)+12-12=60-12
(3xB)=48
Then next step is to isolate the variable within the parentheses. To do this, we must divide both sides by 3.
(3xB)/3=48/3
B=16
