6-\left(2x-1\right)=12x-2\left(x-1\right)
Multiply both sides of the equation by 6, the least common multiple of 6,3.
6-2x-\left(-1\right)=12x-2\left(x-1\right)
To find the opposite of 2x-1, find the opposite of each term.
6-2x+1=12x-2\left(x-1\right)
The opposite of -1 is 1.
7-2x=12x-2\left(x-1\right)
Add 6 and 1 to get 7.
7-2x=12x-2x+2
Use the distributive property to multiply -2 by x-1.
7-2x=10x+2
Combine 12x and -2x to get 10x.
7-2x-10x=2
Subtract 10x from both sides.
7-12x=2
Combine -2x and -10x to get -12x.
-12x=2-7
Subtract 7 from both sides.
-12x=-5
Subtract 7 from 2 to get -5.
x=\frac{-5}{-12}
Divide both sides by -12.
x=\frac{5}{12}
Fraction \frac{-5}{-12} can be simplified to \frac{5}{12} by removing the negative sign from both the numerator and the denominator.
