\frac{1}{310}xz=0.5z
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
\frac{z}{310}x=\frac{z}{2}
The equation is in standard form.
\frac{310\times \frac{z}{310}x}{z}=\frac{z}{2\times \frac{z}{310}}
Divide both sides by \frac{1}{310}z.
x=\frac{z}{2\times \frac{z}{310}}
Dividing by \frac{1}{310}z undoes the multiplication by \frac{1}{310}z.
x=155
Divide \frac{z}{2} by \frac{1}{310}z.
\frac{1}{310}xz=0.5z
Multiply both sides of the equation by x.
\frac{1}{310}xz-0.5z=0
Subtract 0.5z from both sides.
\left(\frac{1}{310}x-0.5\right)z=0
Combine all terms containing z.
\left(\frac{x}{310}-0.5\right)z=0
The equation is in standard form.
z=0
Divide 0 by \frac{1}{310}x-0.5.
