-1-10a<-1 or 10+3a≤ -5

-10a<0 or 3a≤-15

a>0 or a≤-5

-1 - 10a < -1 or 10 + 3a ≤ -5

+1 +1 -10 -10

-10a < 0 or 3a ≤ -15


(-10a)/(-10) > (0)/(-10) or
(3a)/(3) \leq (-15)/(3)

a > 0 or a ≤ -5

notice the left inequality symbol flipped because we divided by a negative

-5 ≥ a > 0

Graph: -5 -------------o 0 (dot is filled at -5 and not filled at 0)
