    x = 2

    Step-by-step explanation:

    Given

    9 (x + 1) = 25 + x ← distribute parenthesis on left side

    9x + 9 = 25 + x (subtract x from both sides)

    8x + 9 = 25 (subtract 9 from both sides)

    8x = 16 (divide both sides by 8)

    x = 2

    x = 2.

    Step-by-step explanation:

    9 (x + 1) = 25 + x

    9x + 9 = 25 + x

    Subtract x from both sides:

    9x - x + 9 = 25

    Subtract 9 from both sides:

    9x - x = 25 - 9

    8x = 16

    x = 16/8 = 2.
