3\left(2x-1\right)+3\left(x+2\right)=2\left(2x+7\right)
Multiply both sides of the equation by 6, the least common multiple of 2,3.
6x-3+3\left(x+2\right)=2\left(2x+7\right)
Use the distributive property to multiply 3 by 2x-1.
6x-3+3x+6=2\left(2x+7\right)
Use the distributive property to multiply 3 by x+2.
9x-3+6=2\left(2x+7\right)
Combine 6x and 3x to get 9x.
9x+3=2\left(2x+7\right)
Add -3 and 6 to get 3.
9x+3=4x+14
Use the distributive property to multiply 2 by 2x+7.
9x+3-4x=14
Subtract 4x from both sides.
5x+3=14
Combine 9x and -4x to get 5x.
5x=14-3
Subtract 3 from both sides.
5x=11
Subtract 3 from 14 to get 11.
x=\frac{11}{5}
Divide both sides by 5.
