Nickels x numbers
\n" ); document.write( "Quarters y numbers
\n" ); document.write( "
\n" ); document.write( "1 x + 1 y = 33 .............1
\n" ); document.write( "5 x + 25 y = 605 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -25
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-25 x -25 y = -825
\n" ); document.write( "5 x 25 y = 605
\n" ); document.write( "Add the two equations
\n" ); document.write( "-20 x = -220
\n" ); document.write( "/ -20
\n" ); document.write( "x = 11
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 33
\n" ); document.write( "11 + 1 y = 33
\n" ); document.write( " 1 y = 33 -11
\n" ); document.write( " 1 y = 22
\n" ); document.write( " y = 22
\n" ); document.write( "Nickels 11 numbers
\n" ); document.write( "Quarters 22 numbers
