show it how I started it
u just divide both sides by 2x thats it
so divide 2x by a + b
put a line then a 2x under a+b
\begin{align*} a+b &= 2xz\\ \frac{a+b}{2x} &=\frac{\cancel{2x}z}{\cancel{2x}}\\ \frac{a+b}{2x} &=z \end{align*}

the answer looks so pretty lol
Ikr thanks so much
but if x = 0 you've got a problem, if a + b = 0 z can be what you want, else z doesn't exist
