    Expressing this expression as a single fraction in lowest terms.

    Could someone please explain this problem for me? I'm pretty stumped.

    Express as single fraction in lowest terms.
    -3+(9t-3z)/(7t)+(7t+4z)/(4t)


    Thanks so much for all your help!

    Hello,

    For example,

    \frac{9t-3z}{7t}=\frac{9{\color{red}t}}{7{\color{red}t}}-\frac{3z}{7t}=\frac 97 - \frac 37 \frac zt
