1. $\"x%2By=3\"$
\n" ); document.write( "2. $\"x-y=4\"$
\n" ); document.write( "Add the equations together to eliminate y,
\n" ); document.write( " $\"x%2By%2Bx-y=3%2B4\"$
\n" ); document.write( " $\"2x=7\"$
\n" ); document.write( " $\"highlight%28x=7%2F2%29\"$
\n" ); document.write( "Then use either equation to solve for y,
\n" ); document.write( " $\"7%2F2%2By=3\"$
\n" ); document.write( " $\"y=6%2F2-7%2F2\"$
\n" ); document.write( " $\"highlight%28y=-1%2F2%29\"$ \n" ); document.write( "
