\n" ); document.write( " 2x + 5y = -1 ..... (1)
\n" ); document.write( " x + 2y = 0 ..... (2)
\n" ); document.write( "(2) * 2, we get (To make one term in both the equations
\n" ); document.write( " 2x + 4y = 0 .....(3) equal.)
\n" ); document.write( "(1) - (3), we get
\n" ); document.write( " y = -1 .........(4)
\n" ); document.write( "Substituting the value of y in Eq.(1), we get
\n" ); document.write( " 2x + (-5) = -1
\n" ); document.write( " So 2x = 5 - 1 = 4
\n" ); document.write( " So x = 4/2
\n" ); document.write( "= x = 2.\r
\n" ); document.write( "\n" ); document.write( "So x=2; y=-1; Answer.
