I need a step-by-step response cause I'm having a hard time understanding.

  • Pre-Algebra -

    5 h – 9 = – 16 + 6 h Add 9 to both sides

    5 h – 9 + 9 = – 16 + 6h + 9

    5 h = – 7 + 6h Subtract 5 h to both sides

    5 h - 5 h = - 7 + 6 h - 5 h

    0 = - 7 + h Add 7 to both sides

    0 + 7 = - 7 + h + 7

    7 = h


    h = 7


    Proof :

    5 h – 9 = – 16 + 6 h

    5 * 7 - 9 = - 16 + 6 * 7

    35 - 9 = - 16 + 42

    26 = 26
