2000-1260-20x\geq 0
Multiply 42 and 30 to get 1260.
740-20x\geq 0
Subtract 1260 from 2000 to get 740.
-20x\geq -740
Subtract 740 from both sides. Anything subtracted from zero gives its negation.
x\leq \frac{-740}{-20}
Divide both sides by -20. Since -20 is negative, the inequality direction is changed.
x\leq 37
Divide -740 by -20 to get 37.
