Question

If 2x-3y=12 and 0≤x≤6 what are the possible values of y

Answer 1

y=2/3x+4

the possible values of y are anything between 0 and 4

x=1,y=2/3
x=2,y=1 1/3
x=3,y=2
x=4,y=2 2/3
x=5,y=3 1/3
x=6,y=4

those are only some of the possible values for x and y but the possible values are any numbers between 0 and 4

Answer 2

-4
`-4 \leq y \leq 0`
