\frac{-2.8}{0.7}\leq q
Divide both sides by 0.7. Since 0.7 is positive, the inequality direction remains the same.
\frac{-28}{7}\leq q
Expand \frac{-2.8}{0.7} by multiplying both numerator and the denominator by 10.
-4\leq q
Divide -28 by 7 to get -4.
q\geq -4
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
