\n" ); document.write( "3y-x=6
\n" ); document.write( "4x+12y=0
\n" ); document.write( "

3y - x = 6______3y - 6 = x -------- eq (i)
\n" );
document.write( "4x + 12y = 0 ------- eq (ii)
\n" );
document.write( "4(3y - 6) + 12y = 0 ------ Substituting 3y - 6 for x in eq (ii)
\n" );
document.write( "12y - 24 + 12y = 0
\n" );
document.write( "12y + 12y = 24
\n" );
document.write( "24y = 24
\n" );
document.write( "y = , or 
\n" );
document.write( "3(1) - 6 = x ------ Substituting 1 for y in eq (i) 
\n" );
document.write( "3 - 6 = x
\n" );
document.write( " \n" );
