nineteen coins consisting of quarters and half-dollars amount to 6.50. find the amount of coins of each kind.
\n" ); document.write( "--------------
\n" ); document.write( "Quantity Eq.:: q + h = 19
\n" ); document.write( "Value Eq:::: 25q+50h = 650 cents
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Multiply thru 1st by 25 to get:
\n" ); document.write( "25q+25h = 25*19
\n" ); document.write( "---
\n" ); document.write( "Subtract that from the Value Eq and solve for \"h\":
\n" ); document.write( "25h = 650-25*19
\n" ); document.write( "25h = 175
\n" ); document.write( "h = 7 (# of half-dollar coins)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"q\"
\n" ); document.write( "q+h = 19
\n" ); document.write( "q+7 = 19
\n" ); document.write( "q = 12 (# of quarters)
