-38a-57+19a\geq 76
Add 19a to both sides.
-19a-57\geq 76
Combine -38a and 19a to get -19a.
-19a\geq 76+57
Add 57 to both sides.
-19a\geq 133
Add 76 and 57 to get 133.
a\leq \frac{133}{-19}
Divide both sides by -19. Since -19 is negative, the inequality direction is changed.
a\leq -7
Divide 133 by -19 to get -7.
