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( "

\n" ); document.write( "Coins equation: p + n + d = 53
\n" ); document.write( "Value equation: p +5n+10d = 277 cents
\n" ); document.write( "Quantity Equation: n-d = 4
\n" ); document.write( "======
\n" ); document.write( "p + n + d + 53
\n" ); document.write( "p +4n+10d = 277
\n" ); document.write( "0 + n - d = 4
\n" ); document.write( "===================
\n" ); document.write( "Solve the system for p,n, and d
