or:You have not asked a question, but you have two equations with three unknowns, so we can do a bit of analysis. First we rewrite the given equations.a = x - 4 The rule is you can do any valid operation on both sides of an equation and it will still be equal. Add 4.a + 4 = xb = x + 4 Subtract 4.b - 4 = x Now set the two equations equal to each other.a + 4 = b - 4 Add 4.a + 8 = b And that is about all we can do until you post your intended question.
