(3,-4) is your x and y. Plug it in the equation so,
For x,
2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5
For y,
2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1

I'm gonna calculate by the area of pizza to see how much food you get for 10 and 20 dollars
A...area
r...radius
d...diameter
d1=12 r1=6
d2=18 r2=9
A1=r1^2×3.14
A1=6^2×3.14
A1=36×3.14
A1=113.04
A2=r2^2×3.13
A2=9^2×3.14
A2=81×3.14
A2=254.34
if you bought 2, 12 diameter pizzas for 20 dollars you would get 226.08 area od food,still less if you bought 1, 18 diameter pizza for 20 dollars. because 223.08 < 254.34
