Your answer would be 0 because you have to subtract 3 by 5 you get the answer 2. Then you subtract 4 by 2 and you 2. After that you multiply 2 by 2 getting the answer 4.
-x + 7 = x - 5 add x to both sides of the equation 7 = 2x - 5 add 5 to both sides of the equation 12 = 2x divide 2 from both sides of the equation 6 = x
