  1. 7x + 3 - 2x....x = 8
       7(8) + 3 - 2(8) = 56 + 3 - 16 = 43

    4. 7 - (-2y) + y - 9....y = 6
         7 - (-2(6) + 6 - 9 = 7 + 12 + 6 - 9 = 16

    7. -x + 8 + 7x - (-1).....x = -10
       -(-10) + 8 + 7(-10) + 1 = 10 + 8 - 70 + 1 = -51

    10. 4x + 2y - x - 8....x = 1, y = 5
          4(1) + 2(5) - 1 - 8 = 4 + 10 - 9 = 5

    13. 2x + 5y - 3x + (-8y)....x = -9, y = 9
          2(-9) + 5(9) - 3(-9) - 8(9) = -18 + 45 + 27 - 72 = -18
