Answer:


x=7

Explanation:


-3x--3+8x-24=6x+7-5x

Two negative signs equate to a positive sign, so we can write
--3 as just
3:


-3x+3+8x-24=6x+7-5x

Add up similar terms:


5x-21=x+7

Add 21 to both sides:


5x-21+21=x+7+21


5x=x+28

Subtract x from both sides:


5x-x=x+28-x


4x=28

Divide both sides by 4:


(4x)/(x) =(28)/(4)


x=7
