30\left(\frac{3x+2}{5}+\frac{1}{2}x\right)-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Multiply both sides of the equation by 30, the least common multiple of 5,2,3,10.
30\times \frac{3x+2}{5}+30\times \frac{1}{2}x-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Use the distributive property to multiply 30 by \frac{3x+2}{5}+\frac{1}{2}x.
6\left(3x+2\right)+30\times \frac{1}{2}x-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Cancel out 5, the greatest common factor in 30 and 5.
18x+12+30\times \frac{1}{2}x-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Use the distributive property to multiply 6 by 3x+2.
18x+12+\frac{30}{2}x-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Multiply 30 and \frac{1}{2} to get \frac{30}{2}.
18x+12+15x-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Divide 30 by 2 to get 15.
33x+12-6\left(x+2-\frac{1}{2}\left(x-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Combine 18x and 15x to get 33x.
33x+12-6\left(x+2-\frac{1}{2}x-\frac{1}{2}\left(-\frac{2}{3}\right)\right)=3\left(3x+1\right)+20x
Use the distributive property to multiply -\frac{1}{2} by x-\frac{2}{3}.
33x+12-6\left(x+2-\frac{1}{2}x+\frac{-\left(-2\right)}{2\times 3}\right)=3\left(3x+1\right)+20x
Multiply -\frac{1}{2} times -\frac{2}{3} by multiplying numerator times numerator and denominator times denominator.
33x+12-6\left(x+2-\frac{1}{2}x+\frac{2}{6}\right)=3\left(3x+1\right)+20x
Do the multiplications in the fraction \frac{-\left(-2\right)}{2\times 3}.
33x+12-6\left(x+2-\frac{1}{2}x+\frac{1}{3}\right)=3\left(3x+1\right)+20x
Reduce the fraction \frac{2}{6} to lowest terms by extracting and canceling out 2.
33x+12-6\left(\frac{1}{2}x+2+\frac{1}{3}\right)=3\left(3x+1\right)+20x
Combine x and -\frac{1}{2}x to get \frac{1}{2}x.
33x+12-6\left(\frac{1}{2}x+\frac{6}{3}+\frac{1}{3}\right)=3\left(3x+1\right)+20x
Convert 2 to fraction \frac{6}{3}.
33x+12-6\left(\frac{1}{2}x+\frac{6+1}{3}\right)=3\left(3x+1\right)+20x
Since \frac{6}{3} and \frac{1}{3} have the same denominator, add them by adding their numerators.
33x+12-6\left(\frac{1}{2}x+\frac{7}{3}\right)=3\left(3x+1\right)+20x
Add 6 and 1 to get 7.
33x+12-6\times \frac{1}{2}x-6\times \frac{7}{3}=3\left(3x+1\right)+20x
Use the distributive property to multiply -6 by \frac{1}{2}x+\frac{7}{3}.
33x+12+\frac{-6}{2}x-6\times \frac{7}{3}=3\left(3x+1\right)+20x
Multiply -6 and \frac{1}{2} to get \frac{-6}{2}.
33x+12-3x-6\times \frac{7}{3}=3\left(3x+1\right)+20x
Divide -6 by 2 to get -3.
33x+12-3x+\frac{-6\times 7}{3}=3\left(3x+1\right)+20x
Express -6\times \frac{7}{3} as a single fraction.
33x+12-3x+\frac{-42}{3}=3\left(3x+1\right)+20x
Multiply -6 and 7 to get -42.
33x+12-3x-14=3\left(3x+1\right)+20x
Divide -42 by 3 to get -14.
30x+12-14=3\left(3x+1\right)+20x
Combine 33x and -3x to get 30x.
30x-2=3\left(3x+1\right)+20x
Subtract 14 from 12 to get -2.
30x-2=9x+3+20x
Use the distributive property to multiply 3 by 3x+1.
30x-2=29x+3
Combine 9x and 20x to get 29x.
30x-2-29x=3
Subtract 29x from both sides.
x-2=3
Combine 30x and -29x to get x.
x=3+2
Add 2 to both sides.
x=5
Add 3 and 2 to get 5.
