    A box contains a total of 14 quarters and dimes -> q+d = 14

    total value is $2.15 -> (.25)*q +(.10)*d=2.15

    to solve a system of equations, you want to solve for one variable in terms of the other and then plug that into the equation you didn't use

    you want to do that to one of them, but you want to get either d = or q = at the end
