Let's say you and a friend went to the mall together. You both bought items at several different stores. When the two of you got back to your house and started looking through your purchases, your friend came across some loose change at the bottom of one of the bags. You said it was yours. Your friend said it was hers.

clues-There are twenty coins altogether.
There are only pennies and nickels.
And the total value of the coins is forty-eight cents.

i need to know how you would write a system of linear equations and solve it by graphing. I know you have 7 nickels and 13 pennies.
