4a-28a+28\leq 196
Use the distributive property to multiply -4 by 7a-7.
-24a+28\leq 196
Combine 4a and -28a to get -24a.
-24a\leq 196-28
Subtract 28 from both sides.
-24a\leq 168
Subtract 28 from 196 to get 168.
a\geq \frac{168}{-24}
Divide both sides by -24. Since -24 is negative, the inequality direction is changed.
a\geq -7
Divide 168 by -24 to get -7.
