Question

If 2 x - 3y = 7 and (a+b)x - (a+b-3)y=4a+b have an infinite number of solutions then the value of a and b are


(a) 5,1
(b) -5,1
(c) 5,-1
(d) -5,-1

Answer 1

Answer:

answer is (d) -5, -1

here the equation will be formed

(2/a+b) =3/(a+b-3) =(7/4a+b) now solve this equation one by one and will will get the answer
