read area
y<-3
(2) blue:
y>3*x-3
red:
y <= 0.5*x + 2

Answer:
If the air trolley ended at 60 km and it traveled 20 km- what was its starting position?
Step-by-step explanation:
Plug y= x+5 in 3x+y= 25, we have:
3x+ (x+5)= 25
⇒ (3x+x)+ 5= 25 (combine like terms)
⇒ 4x= 25-5
⇒ 4x= 20
⇒ x= 20/4
⇒x= 5
y= 5+5= 10
Final answer: x=5, y=10~
