4x+3y=11, 3y-4x=19 solve elimination method

1.	4x+3y=11, 3y-4x=19 solve elimination method
Answer» if one zero of the polynomial FX equal to (k square + 4 )x square + 13 x + 4 k is reciprocal of the other than k= 4x+3y=11........(i)3y-4x=19-4x + 3y = 19 ........(ii)adding (i) and (ii)6y = 30y = 30/6 = 5Put y = 5 in (i)4x + 3(5) = 11\xa04x + 15 = 114x = 11 - 15\xa04x = -4\xa0x = -1\xa0\xa0\xa0
