y-1=x-1

Variable x cannot be equal to 1 since division by zero is not defined. Multiply both sides of the equation by x-1.

x-1=y-1

Swap sides so that all variable terms are on the left hand side.

x=y-1+1

Add 1 to both sides.

x=y

Add -1 and 1 to get 0.

x=y\text{, }x\neq 1

Variable x cannot be equal to 1.

y-1=x-1

Multiply both sides of the equation by x-1.

y=x-1+1

Add 1 to both sides.

y=x

Add -1 and 1 to get 0.
