let the number of nickels be x (nickels, not nickles)

then the number of quarters is x+2

then the number of dimes is 40 - x - (x+2)

or 38-2x

5x + 25(x+2) + 10(38-2x) = 600

solve

Let q = number of quarters

let d = number of dimes

let n = number of nickels.

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

q + d + n = 40

0.25q + 0.10d + 0.05n = 6.00

q = n+2

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

Solve for the three unknowns. Check my thinking.
