2y - x = 3
\n" ); document.write( "x = 3y - 5
\n" ); document.write( "..
\n" ); document.write( "2y-x=3
\n" ); document.write( "x-3y=-5
\n" ); document.write( "..
\n" ); document.write( "Add both the equations
\n" ); document.write( "2y-x+x-3y=3-5
\n" ); document.write( "-y=-2
\n" ); document.write( "y=-2/-1
\n" ); document.write( "y=2
\n" ); document.write( "plug the value of y in any of the equations
\n" ); document.write( "2y-x=3
\n" ); document.write( "2*2-x=3
\n" ); document.write( "4-x=3
\n" ); document.write( "-x=-4+3
\n" ); document.write( "-x=-1
\n" ); document.write( "x=1
\n" ); document.write( "
\n" );
