solve by using elimination method
\n" ); document.write( "x+3y=3 ----(1)
\n" ); document.write( "x+6y=3 ----(2)
\n" ); document.write( "We observe that in both the equations the coefficient of x is 1
\n" ); document.write( "So (1) - (2) will eliminate x
\n" ); document.write( "(x-x)+(3y-6y)= (3-3)
\n" ); document.write( "0-3y = 0
\n" ); document.write( "(-3)y =0
\n" ); document.write( "y= 0/(-3) =0
\n" ); document.write( "Putting y=0 in (1)
\n" ); document.write( "x+3y =3
\n" ); document.write( "x+0=3
\n" ); document.write( "x=3
\n" ); document.write( "Answer: x= 3 and y=0
\n" ); document.write( "Verification:
\n" ); document.write( "The equations and the values are so simple oral verification will do.
\n" ); document.write( "The values are found to be correct. \n" ); document.write( "

\n" );
