You can put this solution on YOUR website!
Typical example for two-variable linear system of equations.

b banana price
n orange price

system%284b%2B5n=2.75%2C6b%2B5n=3.25%29
Use whatever method you know or need.

You can subtract the first equation from the second equation and quickly solve for b.
