8x-24-\left(6-2x\right)=2\left(x+2\right)-5\left(5-x\right)
Use the distributive property to multiply 8 by x-3.
8x-24-6-\left(-2x\right)=2\left(x+2\right)-5\left(5-x\right)
To find the opposite of 6-2x, find the opposite of each term.
8x-24-6+2x=2\left(x+2\right)-5\left(5-x\right)
The opposite of -2x is 2x.
8x-30+2x=2\left(x+2\right)-5\left(5-x\right)
Subtract 6 from -24 to get -30.
10x-30=2\left(x+2\right)-5\left(5-x\right)
Combine 8x and 2x to get 10x.
10x-30=2x+4-5\left(5-x\right)
Use the distributive property to multiply 2 by x+2.
10x-30=2x+4-25+5x
Use the distributive property to multiply -5 by 5-x.
10x-30=2x-21+5x
Subtract 25 from 4 to get -21.
10x-30=7x-21
Combine 2x and 5x to get 7x.
10x-30-7x=-21
Subtract 7x from both sides.
3x-30=-21
Combine 10x and -7x to get 3x.
3x=-21+30
Add 30 to both sides.
3x=9
Add -21 and 30 to get 9.
x=\frac{9}{3}
Divide both sides by 3.
x=3
Divide 9 by 3 to get 3.
