Solve the inequalities -150x ≥ − 2,400 and -336 ≥ − 21y.

Ok so easy peasy
remember that when divide or multiply by negative, reverse the inequality symbol example
2>3 times -1=
-2<-3 so

-150x>-2400
divide both sides by -150
flip sign
x<16

-336>-21y
divide both sides by -21
flip sign
16<y

they seem to have the same solution

x=y>16
