-19+2g\geq 20+5g
Add 19 and 1 to get 20.
-19+2g-5g\geq 20
Subtract 5g from both sides.
-19-3g\geq 20
Combine 2g and -5g to get -3g.
-3g\geq 20+19
Add 19 to both sides.
-3g\geq 39
Add 20 and 19 to get 39.
g\leq \frac{39}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
g\leq -13
Divide 39 by -3 to get -13.
