Answer 3

x+y=240 ... (1)
x=y+80 ...(2)
subst (2) to (1)

Answer 4

x= flax
y= sunflower?

Answer 5

no,
x=sunflower
y= flax

Answer 6

ohh. ok. i want to use s and f. much easier to determine between them.

f=80?

Answer 7

ok, s+f=240 and s=f+80
so, f+80+f=240
2f+80=240
2f=240-80
2f=160
f=160/2=80
u are correct

Answer 8

s=160?

Answer 9

just put f=80 to
s=f+80=80+80=160
correct again :)
