yx=10000
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
\frac{yx}{y}=\frac{10000}{y}
Divide both sides by y.
x=\frac{10000}{y}
Dividing by y undoes the multiplication by y.
x=\frac{10000}{y}\text{, }x\neq 0
Variable x cannot be equal to 0.
