+33653 I'll do the first one for you:
-3 = 1 + x/2
Subtract 1 from both sides
-4 = x/2
Multiply both sides by 2
-8 = x
(or x = -8)
See if you can do the others. First get the term that doesn't multiply or divide x on the other side of the equation, then multiply or divide both sides of the equation by the term that divides or multiplies the x.
