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

-150x>_ -2400

Divide both sides by -150

-150x/-150>_ -2400/-150

x<_ 16


-336>_ -21y

Flip the equation

-21y<_-336

Divide both sides by -21

-21y/-21<_ -336/-21

y>_ 16


I hope that's help !
