    Step-by-step explanation:

    6x + 9 = 57

    6x = 57 - 9

    6x = 48

    x = 48/6

    x = 8

    no ... I dont agree with Amanda.

    I arrived at x = 8 ... and this can be confirmed by subbing in 8 for x back into the original equation.

    6x + 9 = 57 ... x = 8

    6 (8) + 9 = 57

    48 + 9 = 57

    57 = 57 (correct)
