-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.
-23x-36-2\times 4\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Combine -5x and -18x to get -23x.
-23x-36-8\left(2x+1\right)=3\times 3\left(3x+2\right)-40
Multiply -2 and 4 to get -8.
-23x-36-16x-8=3\times 3\left(3x+2\right)-40
Use the distributive property to multiply -8 by 2x+1.
-39x-36-8=3\times 3\left(3x+2\right)-40
Combine -23x and -16x to get -39x.
-39x-44=3\times 3\left(3x+2\right)-40
Subtract 8 from -36 to get -44.
-39x-44=9\left(3x+2\right)-40
Multiply 3 and 3 to get 9.
-39x-44=27x+18-40
Use the distributive property to multiply 9 by 3x+2.
-39x-44=27x-22
Subtract 40 from 18 to get -22.
-39x-44-27x=-22
Subtract 27x from both sides.
-66x-44=-22
Combine -39x and -27x to get -66x.
-66x=-22+44
Add 44 to both sides.
-66x=22
Add -22 and 44 to get 22.
x=\frac{22}{-66}
Divide both sides by -66.
x=-\frac{1}{3}
Reduce the fraction \frac{22}{-66} to lowest terms by extracting and canceling out 22.
