1st: x-y=4
\n" ); document.write( "2nd: 2x+y=5
\n" ); document.write( "----------
\n" ); document.write( "Add 1st and 2nd to get:
\n" ); document.write( "3rd: 3x=9
\n" ); document.write( "x=3
\n" ); document.write( "Substitute into 1st or 2nd to solve for y, as follows:
\n" ); document.write( "3-y=4
\n" ); document.write( "y=-1
\n" ); document.write( "Solution: (3,-1)
