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