    Solving Linear Equations

    Solve:

    <br />
\frac{3}{4} - \frac{x + 1}{12} = \frac{2}{3} - \frac{x - 1}{6}<br />

    Multiplying by 12 you get:

    9 - x + 1 = 8 - 2(x - 1)
    10 - x = 8 - 2x + 2
    10 - x = 10 - 2x
    10 + x = 10

    Therefore x = 0

    The answer says x = 2, I don't know where I went wrong.

    Multiplying by 12 you get:

    Mr F says: 9 - (x + 1) = 8 - 2(x - 1)

    9 - x + 1 = 8 - 2(x - 1) Mr F says: Should be 9 - x - 1 = 8 - 2(x - 1)
