-a\geq 25-70
Subtract 70 from both sides.
-a\geq -45
Subtract 70 from 25 to get -45.
a\leq \frac{-45}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
a\leq 45
Fraction \frac{-45}{-1} can be simplified to 45 by removing the negative sign from both the numerator and the denominator.
