24-8x-1\times 2\left(x+3\times 2\right)=4
Use the distributive property to multiply 8 by 3-x.
24-8x-2\left(x+3\times 2\right)=4
Multiply 1 and 2 to get 2.
24-8x-2\left(x+6\right)=4
Multiply 3 and 2 to get 6.
24-8x-2x-12=4
Use the distributive property to multiply -2 by x+6.
24-10x-12=4
Combine -8x and -2x to get -10x.
12-10x=4
Subtract 12 from 24 to get 12.
-10x=4-12
Subtract 12 from both sides.
-10x=-8
Subtract 12 from 4 to get -8.
x=\frac{-8}{-10}
Divide both sides by -10.
x=\frac{4}{5}
Reduce the fraction \frac{-8}{-10} to lowest terms by extracting and canceling out -2.
