You can put this solution on YOUR website!
y = 2x
\n" ); document.write( "2y - 2x = 2
\n" ); document.write( "Substitute 2x for y
\n" ); document.write( "2(2x) - 2x = 2
\n" ); document.write( "4x - 2x = 2
\n" ); document.write( "2x = 2
\n" ); document.write( "x = 1
\n" ); document.write( "Substitute x = 1 in
\n" ); document.write( "y = 2x
\n" ); document.write( "y = 2(1)
\n" ); document.write( "y = 2
\n" ); document.write( "x = 1 and y = 2
\n" ); document.write( "Hope this helps.
