9-8x+2x\geq 21
Add 2x to both sides.
9-6x\geq 21
Combine -8x and 2x to get -6x.
-6x\geq 21-9
Subtract 9 from both sides.
-6x\geq 12
Subtract 9 from 21 to get 12.
x\leq \frac{12}{-6}
Divide both sides by -6. Since -6 is negative, the inequality direction is changed.
x\leq -2
Divide 12 by -6 to get -2.
