3\left(1\times 4+3\right)x-4\left(2\times 3+2\right)=4\left(1\times 3+1\right)x-2
Multiply both sides of the equation by 12, the least common multiple of 4,3,6.
3\left(4+3\right)x-4\left(2\times 3+2\right)=4\left(1\times 3+1\right)x-2
Multiply 1 and 4 to get 4.
3\times 7x-4\left(2\times 3+2\right)=4\left(1\times 3+1\right)x-2
Add 4 and 3 to get 7.
21x-4\left(2\times 3+2\right)=4\left(1\times 3+1\right)x-2
Multiply 3 and 7 to get 21.
21x-4\left(6+2\right)=4\left(1\times 3+1\right)x-2
Multiply 2 and 3 to get 6.
21x-4\times 8=4\left(1\times 3+1\right)x-2
Add 6 and 2 to get 8.
21x-32=4\left(1\times 3+1\right)x-2
Multiply -4 and 8 to get -32.
21x-32=4\left(3+1\right)x-2
Multiply 1 and 3 to get 3.
21x-32=4\times 4x-2
Add 3 and 1 to get 4.
21x-32=16x-2
Multiply 4 and 4 to get 16.
21x-32-16x=-2
Subtract 16x from both sides.
5x-32=-2
Combine 21x and -16x to get 5x.
5x=-2+32
Add 32 to both sides.
5x=30
Add -2 and 32 to get 30.
x=\frac{30}{5}
Divide both sides by 5.
x=6
Divide 30 by 5 to get 6.
