    P = 2d

    d = 2n ... n = 1/2d

    q = d - 3

    since dimes is mentioned in relation to quarters, pennies, and the nickels, u would use d as ur variable

    ur expression would be : d + (2d) + (1/2d) + (d - 3) = total amount of coins ... then u would solve for d, the number of dimes. And once u know that, u can sub that answer back into ur original equations to find the number of pennies, quarters and nickels
