4x + 3y = 13 ------- eq (i)
\n" );
document.write( "2x - 7y = 15 ------- eq (ii)
\n" );
document.write( "- 4x + 14y = - 30 ------- Multiplying eq (ii) by - 2 ------- eq (iii)
\n" );
document.write( "17y = - 17 ------- Adding eqs (iii) and (i)
\n" );

document.write( "\n" );
document.write( "4x + 3(- 1) = 13 ----- Substituting - 1 for y in eq (i)
