The problem is 6 + -x/2 = 14 My answer is x = 16. The "correct" answer is -16 but I don't understand this solution.

  • Pre-Algebra -

    6+ -x/2=14
    6-x/2 = 14
    multiply both sides by 2
    2*6 -2(x/2) = 2*14
    move 12 to right hand side.
    combine terms
    multiply both sides by -1 (to get +x and not -x)
    x = -16
