Hi there,
\n" ); document.write( "Make Nickels = x
\n" ); document.write( "and Quarters = y
\n" ); document.write( "x = y = 61.......(1)
\n" ); document.write( "5x + 25y = 565......(2)
\n" ); document.write( "Multiply Eq(1) by 25
\n" ); document.write( "25x + 25y = 1525.....(1)
\n" ); document.write( "5x + 25y = 565.......(2)
\n" ); document.write( "Subtract Eq(2) from Eq(1)
\n" ); document.write( "20x = 960
\n" ); document.write( "x = 48
\n" ); document.write( "Substitute x = 48 into Eq(1)
\n" ); document.write( "x + y = 61
\n" ); document.write( "48 + y = 61
\n" ); document.write( "y = 61 - 48
\n" ); document.write( "y = 13
\n" ); document.write( "Kevin and Randy had:-
\n" ); document.write( "48 Nickels and 13 Quarters.
\n" ); document.write( "Hope this helps:-)
