yx=1x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
yx-x=0
Subtract 1x from both sides.
\left(y-1\right)x=0
Combine all terms containing x.
x=0
Divide 0 by y-1.
x\in \emptyset
Variable x cannot be equal to 0.
y=\frac{x}{x}
Express \frac{1}{x}x as a single fraction.
y=1
Cancel out x in both numerator and denominator.
