Question

Suppose that bob has 35 coins consisting of nickels,dimes and quarters.The number of dimes is 4 less than twice the number of nickels,and the number of quarters is 3 less than three times the number of nickels.Find the number of coins of each denomination.

Answer 1

x = number of nickels

2x - 4 = number of dimes

3x - 3 = number of quarters

x + (2x - 4) + (3x - 3) = 35

Solve for x and finish from here.
