6x+3\left(3\times 2+1\right)=2\left(4\times 3+2\right)
Multiply both sides of the equation by 6, the least common multiple of 2,3.
6x+3\left(6+1\right)=2\left(4\times 3+2\right)
Multiply 3 and 2 to get 6.
6x+3\times 7=2\left(4\times 3+2\right)
Add 6 and 1 to get 7.
6x+21=2\left(4\times 3+2\right)
Multiply 3 and 7 to get 21.
6x+21=2\left(12+2\right)
Multiply 4 and 3 to get 12.
6x+21=2\times 14
Add 12 and 2 to get 14.
6x+21=28
Multiply 2 and 14 to get 28.
6x=28-21
Subtract 21 from both sides.
6x=7
Subtract 21 from 28 to get 7.
x=\frac{7}{6}
Divide both sides by 6.
