-12x+3=6-\left(11-6x\right)
Multiply both sides of the equation by 6, the least common multiple of 2,6.
-12x+3=6-11-\left(-6x\right)
To find the opposite of 11-6x, find the opposite of each term.
-12x+3=6-11+6x
The opposite of -6x is 6x.
-12x+3=-5+6x
Subtract 11 from 6 to get -5.
-12x+3-6x=-5
Subtract 6x from both sides.
-18x+3=-5
Combine -12x and -6x to get -18x.
-18x=-5-3
Subtract 3 from both sides.
-18x=-8
Subtract 3 from -5 to get -8.
x=\frac{-8}{-18}
Divide both sides by -18.
x=\frac{4}{9}
Reduce the fraction \frac{-8}{-18} to lowest terms by extracting and canceling out -2.
