You can put this solution on YOUR website!
Add them together to eliminate $\"y\"$ .
\n" ); document.write( " $\"x-y%2Bx%2By=2%2B1\"$
\n" ); document.write( " $\"2x=3\"$
\n" ); document.write( " $\"x=3%2F2\"$
\n" ); document.write( "Then use either equation to solve for $\"x\"$ .
\n" ); document.write( " $\"x-y=2\"$
\n" ); document.write( " $\"3%2F2-y=2\"$
\n" ); document.write( " $\"-y=4%2F2-3%2F2\"$
\n" ); document.write( " $\"-y=1%2F2\"$
\n" ); document.write( " $\"y=-1%2F2\"$
\n" ); document.write( " \n" ); document.write( "
