20 POINTS!!!! A small fruit basket costs $8 and a large basket costs $20. The small basket contains 6 apples and 4 pears. The large basket contains 18 apples and 12 pears. Write a system of linear equations to represent this situation. Can you find the unit price of each fruit? Explain.

So this is a question I have on my math homework I solved the first part and got 6x+4y=8 and 18x+12y=20 for the system of linear equations but i don't understand how to find out if it is possible to find the unit price of each fruit. Please help!
