4\left(3x-1\right)+12=3\left(3x+5\right)-2\left(x-4\right)-6\left(2\times 2+1\right)
Multiply both sides of the equation by 12, the least common multiple of 3,4,6,2.
12x-4+12=3\left(3x+5\right)-2\left(x-4\right)-6\left(2\times 2+1\right)
Use the distributive property to multiply 4 by 3x-1.
12x+8=3\left(3x+5\right)-2\left(x-4\right)-6\left(2\times 2+1\right)
Add -4 and 12 to get 8.
12x+8=9x+15-2\left(x-4\right)-6\left(2\times 2+1\right)
Use the distributive property to multiply 3 by 3x+5.
12x+8=9x+15-2x+8-6\left(2\times 2+1\right)
Use the distributive property to multiply -2 by x-4.
12x+8=7x+15+8-6\left(2\times 2+1\right)
Combine 9x and -2x to get 7x.
12x+8=7x+23-6\left(2\times 2+1\right)
Add 15 and 8 to get 23.
12x+8=7x+23-6\left(4+1\right)
Multiply 2 and 2 to get 4.
12x+8=7x+23-6\times 5
Add 4 and 1 to get 5.
12x+8=7x+23-30
Multiply -6 and 5 to get -30.
12x+8=7x-7
Subtract 30 from 23 to get -7.
12x+8-7x=-7
Subtract 7x from both sides.
5x+8=-7
Combine 12x and -7x to get 5x.
5x=-7-8
Subtract 8 from both sides.
5x=-15
Subtract 8 from -7 to get -15.
x=\frac{-15}{5}
Divide both sides by 5.
x=-3
Divide -15 by 5 to get -3.
