    As always, ask what you need to do to get x by itself.
    \frac{x}{2} = \frac{7}{8}

    2 \cdot \frac{x}{2} = 2 \cdot \frac{7}{8}

    x = \frac{2 \cdot 7}{8} = \frac{7}{4}

    x \cdot \frac{2}{3} = x \cdot \frac{3}{x}

    \frac{2x}{3} = 3

    \frac{3}{2} \cdot \frac{2x}{3} = \frac{3}{2} \cdot 3

    x = \frac{9}{2}

    \frac{2}{9}x = 7

    \frac{9}{2} \cdot \frac{2}{9}x = \frac{9}{2} \cdot 7

    x = \frac{63}{2}
