5xz=-5
Multiply both sides of the equation by z.
5zx=-5
The equation is in standard form.
\frac{5zx}{5z}=-\frac{5}{5z}
Divide both sides by 5z.
x=-\frac{5}{5z}
Dividing by 5z undoes the multiplication by 5z.
x=-\frac{1}{z}
Divide -5 by 5z.
5xz=-5
Variable z cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by z.
\frac{5xz}{5x}=-\frac{5}{5x}
Divide both sides by 5x.
z=-\frac{5}{5x}
Dividing by 5x undoes the multiplication by 5x.
z=-\frac{1}{x}
Divide -5 by 5x.
z=-\frac{1}{x}\text{, }z\neq 0
Variable z cannot be equal to 0.
