-2zx+5=0
Combine zx and -3zx to get -2zx.
-2zx=-5
Subtract 5 from both sides. Anything subtracted from zero gives its negation.
\left(-2z\right)x=-5
The equation is in standard form.
\frac{\left(-2z\right)x}{-2z}=-\frac{5}{-2z}
Divide both sides by -2z.
x=-\frac{5}{-2z}
Dividing by -2z undoes the multiplication by -2z.
x=\frac{5}{2z}
Divide -5 by -2z.
