Note, I turned the mixed fraction into an improper fraction. This will make it much easier to work with.
There are two terms on the left side:
and
. Only one of them has a Z in it, so lets move it to the right side of the equals sign. We can do this by subtracting each side by
.
We can then combine like terms:
Then, we can divide each side by 2 to turn 2z into z:
Therefore,![z=\frac{14}{8} = 1.75](/tpl/images/0466/6714/55f4a.png)
