You can put this solution on YOUR website!
Solve by using one of the ordered pairs and solve, see if you get the other
\n" ); document.write( "x+2y=2
\n" ); document.write( "0+2y=2
\n" ); document.write( "y=2/2
\n" ); document.write( "y=1
\n" ); document.write( "first one works
\n" ); document.write( "2+2y=2
\n" ); document.write( "2y=0
\n" ); document.write( "y=0
\n" ); document.write( "second one works
\n" ); document.write( "x+2*-1=2
\n" ); document.write( "x=-2=2
\n" ); document.write( "x=4
\n" ); document.write( "three does not work
\n" ); document.write( "you do the last one
\n" ); document.write( "
