A = small box of oranges
B = large box of oranges
3A + 14B = 203
11A + 11B = 220
Take the second equation and divide it by 11 as both A and B have the same coefficient, which will equal:
[tex]\frac{11A+11B}{11}[/tex] = A + B
220 will also have to be divided by 11, giving you 20
A + B = 20
You can cancel out 3A in the first equation by subtracting 3A + 3B = 60 from it.
11B = 143
143/11 = 13
B (large box of oranges) costs $13.
Substitute 13 for B back into one of our equations, in this case 3A + 3B = 60
3A + 3*13 = 60
3A + 39 = 60
3A = 21
A = 7
Thus:
A small box of oranges costs $7, and a large box of oranges costs $13.
