You can put this solution on YOUR website!
Add the equations together to eliminate $\"y\"$ .
\n" ); document.write( " $\"x%2By%2Bx-y=0%2B1\"$
\n" ); document.write( " $\"2x=1\"$
\n" ); document.write( " $\"highlight%28x=1%2F2%29\"$
\n" ); document.write( "Then use either equation to solve for $\"y\"$ .
\n" ); document.write( " $\"1%2F2%2By=0\"$
\n" ); document.write( " $\"highlight%28y=-1%2F2%29\"$ \n" ); document.write( "
