I started with # of dimes x + 5, # of quarters is x, # of nickels is x-4. I formed this equation .10(x+5) + .25x + .05 (x+4) = 34, then I multiplied by 100 to get 10x + 50 + 25x + 5x +20 = 34, 40x + 30 =34. I have no idea what I'm doing. \n" ); document.write( "

Sam has 5 more dimes than quarters and four less nickels than quarters.
\n" ); document.write( "d = q + 5
\n" ); document.write( "n = q -4
\n" ); document.write( "--------------------
\n" ); document.write( "If he has 34 coins, how many of each does he have?
\n" ); document.write( "n + d + q = 34
\n" ); document.write( "==========================
\n" ); document.write( "Substitute for d and n and solve for \"q\":
\n" ); document.write( "q-4 + q+5 + q = 34
\n" ); document.write( "3q +1 = 34
\n" ); document.write( "3q = 33
\n" ); document.write( "q = 11 (# of quarters)
\n" ); document.write( "---
\n" ); document.write( "d = q+5 = 16 (# of dimes)
\n" ); document.write( "n = q-4 = 7 (# of nickels)
\n" ); document.write( "===============================
