Xy=49
x-y=13
x=13+y
y(13+y)=49
y²+13y-49=0
solve using the quadratic formula
Answer:

Step-by-step explanation:
We can set up the following system of equations:
, where
is the number of dimes she has and
is the number of nickels she has.
Multiplying the second equation by -5 and adding both equations lets us isolate and solve for
:

Plugging
into any of the two equations will let us solve for
:
.
Therefore, she has 14 nickels.
