7x+20-10x\leq 8
Subtract 10x from both sides.
-3x+20\leq 8
Combine 7x and -10x to get -3x.
-3x\leq 8-20
Subtract 20 from both sides.
-3x\leq -12
Subtract 20 from 8 to get -12.
x\geq \frac{-12}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
x\geq 4
Divide -12 by -3 to get 4.
