Answer: x+y = 40

We have a = 1, b = 1, c = 40

=================================

Explanation:

x = number of nickels

y = number of quarters

The equation 0.05x+0.25y = 5 represents adding the values from the nickels and quarters

0.05x = value of just the nickels

0.25y = value of just the quarters

0.05x+0.25y = total value = 5 dollars

That's how that first equation was formed.

-------------

Based on those x and y definitions above, we know that x+y = 40 because there are 40 coins of either nickels or quarters only. So the sum of the two coin counts must be 40 overall.

The equation x+y = 40 is the same as 1x+1y = 40. This equation is in the form ax+by = c where,

a = 1

b = 1

c = 40
