Answer:
In first equation if we put the value of x and y (x=2,y=2)than,
3x+y=8
3×x+y=8
3×2+2=8
6+2=8
8=8
in second equation the value of x=2,y=1
x2+xy=6
x2+x×y=6
4+2×1=6
4+2=6
6=6

You are going to divide 366 by 12 you get 30.5 so 30 filled cartons
are you sure it's not 336 eggs??
I dont know how to this but you probably make 4 3/8 and 2 1/2 into a decimal add all them together...
I believe it could be option 1
