4x+20-\left(12x+24\right)=12\left(x+1\right)+6\left(x+8\right)
Multiply both sides of the equation by 24, the least common multiple of 24,2,4.
4x+20-12x-24=12\left(x+1\right)+6\left(x+8\right)
To find the opposite of 12x+24, find the opposite of each term.
-8x+20-24=12\left(x+1\right)+6\left(x+8\right)
Combine 4x and -12x to get -8x.
-8x-4=12\left(x+1\right)+6\left(x+8\right)
Subtract 24 from 20 to get -4.
-8x-4=12x+12+6\left(x+8\right)
Use the distributive property to multiply 12 by x+1.
-8x-4=12x+12+6x+48
Use the distributive property to multiply 6 by x+8.
-8x-4=18x+12+48
Combine 12x and 6x to get 18x.
-8x-4=18x+60
Add 12 and 48 to get 60.
-8x-4-18x=60
Subtract 18x from both sides.
-26x-4=60
Combine -8x and -18x to get -26x.
-26x=60+4
Add 4 to both sides.
-26x=64
Add 60 and 4 to get 64.
x=\frac{64}{-26}
Divide both sides by -26.
x=-\frac{32}{13}
Reduce the fraction \frac{64}{-26} to lowest terms by extracting and canceling out 2.
