    Determine whether the equation is a linear equation..Help!

    1. \frac{x}{2} = 10 + \frac{2y}{3}

    2. 7n - 8m = 4 - 2m

    I guess both are linear, because

    \frac{x}{2} = 10 + \frac{2y}{3}

    y = \frac{3}{2}(\frac{x}{2}-10)

    and

    7n - 8m = 4 - 2m

    6m = 4 - 7n

     m = \frac{4-7n}{6}

    This is a straight line, too
