2-4x-24=5x-8
Use the distributive property to multiply -4 by x+6.
-22-4x=5x-8
Subtract 24 from 2 to get -22.
-22-4x-5x=-8
Subtract 5x from both sides.
-22-9x=-8
Combine -4x and -5x to get -9x.
-9x=-8+22
Add 22 to both sides.
-9x=14
Add -8 and 22 to get 14.
x=\frac{14}{-9}
Divide both sides by -9.
x=-\frac{14}{9}
Fraction \frac{14}{-9} can be rewritten as -\frac{14}{9} by extracting the negative sign.
