1) To solve for x, is to let x on the left side and the other terms and variables on the right side.
bx -10=f <em>Add 10 to both sides</em>
bx = f+10 Divide by b on both sides
So that's the way we solve for x.
b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.
z = 2h +2b
