\pi =8y
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y.
8y=\pi
Swap sides so that all variable terms are on the left hand side.
\frac{8y}{8}=\frac{\pi }{8}
Divide both sides by 8.
y=\frac{\pi }{8}
Dividing by 8 undoes the multiplication by 8.
y=\frac{\pi }{8}\text{, }y\neq 0
Variable y cannot be equal to 0.
