    Coin Word Problem
    I have to solve a coin word problem using a method called HES (Heading, Equation, Solution). In the problem, there are 3 unknowns and we have to have 2 equations so that we can either use substitution or elimination.
    I have to let x=?(something)
    2x=?(something)
    y=? (something)
    The word problems is as follows:
