9\left(x+\frac{2x+1}{3}\right)-3\left(x-\frac{2x+1}{3}\right)=15\left(2x-\frac{2x+1}{3}\right)+111
Multiply both sides of the equation by 3.
9x+9\times \frac{2x+1}{3}-3\left(x-\frac{2x+1}{3}\right)=15\left(2x-\frac{2x+1}{3}\right)+111
Use the distributive property to multiply 9 by x+\frac{2x+1}{3}.
9x+3\left(2x+1\right)-3\left(x-\frac{2x+1}{3}\right)=15\left(2x-\frac{2x+1}{3}\right)+111
Cancel out 3, the greatest common factor in 9 and 3.
9x+6x+3-3\left(x-\frac{2x+1}{3}\right)=15\left(2x-\frac{2x+1}{3}\right)+111
Use the distributive property to multiply 3 by 2x+1.
15x+3-3\left(x-\frac{2x+1}{3}\right)=15\left(2x-\frac{2x+1}{3}\right)+111
Combine 9x and 6x to get 15x.
15x+3-3\left(x-\frac{2x+1}{3}\right)=30x+15\left(-\frac{2x+1}{3}\right)+111
Use the distributive property to multiply 15 by 2x-\frac{2x+1}{3}.
15x+3-3\left(x-\frac{2x+1}{3}\right)=30x-5\left(2x+1\right)+111
Cancel out 3, the greatest common factor in 15 and 3.
15x+3-3\left(x-\frac{2x+1}{3}\right)=30x-10x-5+111
Use the distributive property to multiply -5 by 2x+1.
15x+3-3\left(x-\frac{2x+1}{3}\right)=20x-5+111
Combine 30x and -10x to get 20x.
15x+3-3\left(x-\frac{2x+1}{3}\right)=20x+106
Add -5 and 111 to get 106.
15x+3-3\left(x-\left(\frac{2}{3}x+\frac{1}{3}\right)\right)=20x+106
Divide each term of 2x+1 by 3 to get \frac{2}{3}x+\frac{1}{3}.
15x+3-3\left(x-\frac{2}{3}x-\frac{1}{3}\right)=20x+106
To find the opposite of \frac{2}{3}x+\frac{1}{3}, find the opposite of each term.
15x+3-3\left(\frac{1}{3}x-\frac{1}{3}\right)=20x+106
Combine x and -\frac{2}{3}x to get \frac{1}{3}x.
15x+3-3\times \frac{1}{3}x-3\left(-\frac{1}{3}\right)=20x+106
Use the distributive property to multiply -3 by \frac{1}{3}x-\frac{1}{3}.
15x+3-x-3\left(-\frac{1}{3}\right)=20x+106
Multiply -3 times \frac{1}{3}.
15x+3-x+1=20x+106
Multiply -3 times -\frac{1}{3}.
14x+3+1=20x+106
Combine 15x and -x to get 14x.
14x+4=20x+106
Add 3 and 1 to get 4.
14x+4-20x=106
Subtract 20x from both sides.
-6x+4=106
Combine 14x and -20x to get -6x.
-6x=106-4
Subtract 4 from both sides.
-6x=102
Subtract 4 from 106 to get 102.
x=\frac{102}{-6}
Divide both sides by -6.
x=-17
Divide 102 by -6 to get -17.
