You can put this solution on YOUR website!
From the second equation , we get \r
\n" ); document.write( "\n" ); document.write( "y=2x-5.
\n" ); document.write( "Substituting y=2x-5 in the first equation , we get
\n" ); document.write( "x^2-2x+5=4x \r
\n" ); document.write( "\n" ); document.write( "or, x^2-6x+5=0,
\n" ); document.write( "or, x^2-5x-x+5=0,
\n" ); document.write( "or, (x-5)(x-1)=0,
\n" ); document.write( "or, x=5,1
\n" ); document.write( "If x=5 , then y=5,
\n" ); document.write( "If x=1, then y=-3, Thus the solutions are (5,5) or (1,-3)
\n" ); document.write( "
\n" );
