2.8+0.07x-0.09x\geq 0
Subtract 0.09x from both sides.
2.8-0.02x\geq 0
Combine 0.07x and -0.09x to get -0.02x.
-0.02x\geq -2.8
Subtract 2.8 from both sides. Anything subtracted from zero gives its negation.
x\leq \frac{-2.8}{-0.02}
Divide both sides by -0.02. Since -0.02 is negative, the inequality direction is changed.
x\leq \frac{-280}{-2}
Expand \frac{-2.8}{-0.02} by multiplying both numerator and the denominator by 100.
x\leq 140
Divide -280 by -2 to get 140.
