5x-6\times 3\left(x+2\right)-2\times 4\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Multiply both sides of the equation by 30, the least common multiple of 6,5,15,10,3.
5x-18\left(x+2\right)-2\times 4\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Multiply -6 and 3 to get -18.
5x-18x-36-2\times 4\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Use the distributive property to multiply -18 by x+2.
-13x-36-2\times 4\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Combine 5x and -18x to get -13x.
-13x-36-8\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Multiply -2 and 4 to get -8.
-13x-36-16x-8=3\times 3\left(3x+2\right)-40
Use the distributive property to multiply -8 by 2x+1.
-29x-36-8=3\times 3\left(3x+2\right)-40
Combine -13x and -16x to get -29x.
-29x-44=3\times 3\left(3x+2\right)-40
Subtract 8 from -36 to get -44.
-29x-44=9\left(3x+2\right)-40
Multiply 3 and 3 to get 9.
-29x-44=27x+18-40
Use the distributive property to multiply 9 by 3x+2.
-29x-44=27x-22
Subtract 40 from 18 to get -22.
-29x-44-27x=-22
Subtract 27x from both sides.
-56x-44=-22
Combine -29x and -27x to get -56x.
-56x=-22+44
Add 44 to both sides.
-56x=22
Add -22 and 44 to get 22.
x=\frac{22}{-56}
Divide both sides by -56.
x=-\frac{11}{28}
Reduce the fraction \frac{22}{-56} to lowest terms by extracting and canceling out 2.
