2x - 3y = 4 given' will have infinite number of
solution?
(a) 10
(b) – 12
(c) 12
(d) None of these
14.
​

Answer 1

Answer

c)12

right answer is 12

hope this answer useful to you

Answer 2

For infinite number of solutions,

A1/A2 = B1/B2 = C1/C2

=> 6/2 = -9 /-3 = m/4

=> 3 = 3 = m/4

=> m = 3 × 4

=> m = 12
