y=x+2
\n" ); document.write( "y+1=2x
\n" ); document.write( "replace y with (x+2) in the second equation & solve for x.
\n" ); document.write( "(x+2)+1=2x
\n" ); document.write( "x+2+1-2x=0
\n" ); document.write( "-x=-3
\n" ); document.write( "x=3 ans.
\n" ); document.write( "y+1=2*3
\n" ); document.write( "y+1=6
\n" ); document.write( "y=6-1
\n" ); document.write( "y=5 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "5+1=2*3
\n" ); document.write( "6=6 \n" ); document.write( "
