x-1+x\times 2x=2x\left(x-1\right)
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,x-1.
x-1+x^{2}\times 2=2x\left(x-1\right)
Multiply x and x to get x^{2}.
x-1+x^{2}\times 2=2x^{2}-2x
Use the distributive property to multiply 2x by x-1.
x-1+x^{2}\times 2-2x^{2}=-2x
Subtract 2x^{2} from both sides.
x-1=-2x
Combine x^{2}\times 2 and -2x^{2} to get 0.
x-1+2x=0
Add 2x to both sides.
3x-1=0
Combine x and 2x to get 3x.
3x=1
Add 1 to both sides. Anything plus zero gives itself.
x=\frac{1}{3}
Divide both sides by 3.
