    If you're solving for x, the answer is - 50. x = - 50

    Step-by-step explanation:

    Remove the parenthesis and distribute:

    -5 (x-8) + 7 (x+3) = x + 11

    -5x + 40 * + 7 (x+3) = x + 11

    -5x + 40 + 7x + 21 * = x + 11

    Collect like terms and calculate:

    | - 5x + 7x

    2x + 40 + 21 = x + 11

    | 40 + 21

    2x + 61 = x + 11

    Move them to the other side like so:

    2x - x * + 61 = 11

    | - 61

    2x - x = 11 - 61

    Combine:

    x = 11 - 61

    x = - 50
