document.write( "Question 796865: Beth has $2.77 in her coin jar - all in pennies (x), nickels (y) and dimes (z). If she has 53 coins in all and four more nickels than dimes, find how many of each type of coin she has. Setup three equations in x, y, and z and solve the equations to find x(pennies), y(nickels), and z(dimes). Note only one equation has y and z only. I do not even know where to begin, once I find the equation I know how to solve them..I just cant find the equaitons \n" ); document.write( "
