12-\left(2x+1\right)+4\left(2x-1\right)=3\left(10x+1\right)
Multiply both sides of the equation by 12, the least common multiple of 12,3,4.
12-2x-1+4\left(2x-1\right)=3\left(10x+1\right)
To find the opposite of 2x+1, find the opposite of each term.
11-2x+4\left(2x-1\right)=3\left(10x+1\right)
Subtract 1 from 12 to get 11.
11-2x+8x-4=3\left(10x+1\right)
Use the distributive property to multiply 4 by 2x-1.
11+6x-4=3\left(10x+1\right)
Combine -2x and 8x to get 6x.
7+6x=3\left(10x+1\right)
Subtract 4 from 11 to get 7.
7+6x=30x+3
Use the distributive property to multiply 3 by 10x+1.
7+6x-30x=3
Subtract 30x from both sides.
7-24x=3
Combine 6x and -30x to get -24x.
-24x=3-7
Subtract 7 from both sides.
-24x=-4
Subtract 7 from 3 to get -4.
x=\frac{-4}{-24}
Divide both sides by -24.
x=\frac{1}{6}
Reduce the fraction \frac{-4}{-24} to lowest terms by extracting and canceling out -4.
