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( " |
