A = 47900
i = 5% = .05
n = number of compounding periods in a year (1,2,12,365)
t = number of years = 5
To clarify the systems of equations:
We already have opposite coefficients for y, so combine the two equations together:
Divide both sides by 5 to get x by itself:
Because we now know x, we can plug it into one of the equations.
We will plug this value into the first equation:
Add 24 to both sides.
Divide both sides by -1 to get y by itself.
Using elimination, x = 2 and y = -30.
