xx+x\left(x-1\right)\left(-1\right)=\left(x-1\right)\times 2
Variable x cannot be equal to any of the values 0,1 since division by zero is not defined. Multiply both sides of the equation by x\left(x-1\right), the least common multiple of x-1,x.
x^{2}+x\left(x-1\right)\left(-1\right)=\left(x-1\right)\times 2
Multiply x and x to get x^{2}.
x^{2}+\left(x^{2}-x\right)\left(-1\right)=\left(x-1\right)\times 2
Use the distributive property to multiply x by x-1.
x^{2}-x^{2}+x=\left(x-1\right)\times 2
Use the distributive property to multiply x^{2}-x by -1.
x=\left(x-1\right)\times 2
Combine x^{2} and -x^{2} to get 0.
x=2x-2
Use the distributive property to multiply x-1 by 2.
x-2x=-2
Subtract 2x from both sides.
-x=-2
Combine x and -2x to get -x.
x=2
Multiply both sides by -1.
