Question

Find the value of ‘a’ for which the pair of linear equations 2x + 3y = 7 and 4x + ay =
14 has infinitely many solutions.

Answer 1

here is your answer pls mark me as brainliest

Answer 2

If two eq have infinite many sol . Than a1/a2 = b1/b2 = c1/c2

So,2/4 =3/a=7/14

Than 3/a = 1/2

So, 1/a = 1/6

Therefore,a=6
