7) 5x + 16.50 = 59            -16.50    -16.50 (Subtract 16.50 from both sides)                  5x = 42.50                  /5      /5       (Divide by 5 on both sides)                     x = $8.50 8) 4 + 3x = 67       -4         -4            3x = 63             /3     /3              x = 21 stuffed animals 9) 20 + 3x = -4       -20         -20              3x = -24               /3     /3                x = -8 10) 18.9 - 2x = 9.9        -18.9         -18.9                -2x = -9                /-2     /-2                   x = 4.5 (I'm not completely sure on number 10, but I hope this helps!)
