60a+64-80a>-92
Subtract 80a from both sides.
-20a+64>-92
Combine 60a and -80a to get -20a.
-20a>-92-64
Subtract 64 from both sides.
-20a>-156
Subtract 64 from -92 to get -156.
a<\frac{-156}{-20}
Divide both sides by -20. Since -20 is negative, the inequality direction is changed.
a<\frac{39}{5}
Reduce the fraction \frac{-156}{-20} to lowest terms by extracting and canceling out -4.
