\left(x-1\right)\left(3x-1\right)-3\times 2x=x\times 3\left(x-1\right)
Variable x cannot be equal to 1 since division by zero is not defined. Multiply both sides of the equation by 3\left(x-1\right), the least common multiple of 3,x-1.
3x^{2}-4x+1-3\times 2x=x\times 3\left(x-1\right)
Use the distributive property to multiply x-1 by 3x-1 and combine like terms.
3x^{2}-4x+1-6x=x\times 3\left(x-1\right)
Multiply -3 and 2 to get -6.
3x^{2}-10x+1=x\times 3\left(x-1\right)
Combine -4x and -6x to get -10x.
3x^{2}-10x+1=3x^{2}-x\times 3
Use the distributive property to multiply x\times 3 by x-1.
3x^{2}-10x+1=3x^{2}-3x
Multiply -1 and 3 to get -3.
3x^{2}-10x+1-3x^{2}=-3x
Subtract 3x^{2} from both sides.
-10x+1=-3x
Combine 3x^{2} and -3x^{2} to get 0.
-10x+1+3x=0
Add 3x to both sides.
-7x+1=0
Combine -10x and 3x to get -7x.
-7x=-1
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-1}{-7}
Divide both sides by -7.
x=\frac{1}{7}
Fraction \frac{-1}{-7} can be simplified to \frac{1}{7} by removing the negative sign from both the numerator and the denominator.
