\n" ); document.write( "Solve each pair of equation given below using elimination method:X+2y=-4. 3x-5y=-1
\n" ); document.write( "
I'm assuming that X is same as x. Do not write X and x as they signify 2 DIFFERENT variables
\n" );
document.write( "x + 2y = - 4 ------- eq (i)
\n" );
document.write( "3x - 5y = - 1 ------ eq (ii)
\n" );
document.write( "- 3x - 6y = 12 ----- Multiplying eq (i) by - 3 ------ eq (iii)
\n" );
document.write( "   - 11y = 11 ------ Adding eqs (iii) & (ii)
\n" );

\n" );
document.write( "Substitute - 1 for y into any of the 2 original equations to get the value of x. \n" );
