    Can anyone help solve this equation just don’t understand the steps to get to the answer:

    Y=4500/P+625+87.5[(5821.43-Y)/28.57]

    The answer is Y=1107.69/P+4542.31

    Thank you,

    Here you go:

    Y = 4500/P + 625 + 87.5[(5821.43-Y)/28.57]

    Y = 4500/P + 625 + 17829.02 – 3.06Y

    4.06Y = 4500/P + 18454.02

    Y = 1108.4/P + 4545.3

    I know it’s not exactly the answer you provided but given rounding error it’s close enough.
