Solve for z
z=-\frac{x}{5}+\frac{2}{5}+\frac{1}{x}
x\neq 0
Solve for x
x=\frac{\sqrt{25z^{2}-20z+24}}{2}-\frac{5z}{2}+1
x=-\frac{\sqrt{25z^{2}-20z+24}}{2}-\frac{5z}{2}+1

2x+5-5xz=x^{2}
Swap sides so that all variable terms are on the left hand side.
5-5xz=x^{2}-2x
Subtract 2x from both sides.
-5xz=x^{2}-2x-5
Subtract 5 from both sides.
\left(-5x\right)z=x^{2}-2x-5
The equation is in standard form.
\frac{\left(-5x\right)z}{-5x}=\frac{x^{2}-2x-5}{-5x}
Divide both sides by -5x.
z=\frac{x^{2}-2x-5}{-5x}
Dividing by -5x undoes the multiplication by -5x.
z=-\frac{x}{5}+\frac{2}{5}+\frac{1}{x}
Divide x^{2}-2x-5 by -5x.
