Step-by-step explanation:
1680 dollars would be their pay
Since one nickel equals 5 cents, you'd multiply 10 nickels by 5 cents apiece and yield 50 cents to spend.
Equate real part and imaginary part:
LHS:
real part -- 12
imaginary part -- 5y
RHS:
real part = 4x
imaginary part = 25
Equating::
12 = 4x
x = 12/4
x = 3
Again:
5y = 25
y = 25/5
y = 5
So,
x = 3
y = 5
