Question

If 12A + 6AB = A09, then the value of A and B is

Answer 1

Given:

12A + 6AB = A09

Or, 6A(2+B) = A09

Or, 6(2+B) = 9

Or, 2 +B = 9/6

Or, B = 9/6 - 2/1

Or, B = - 3/6

ie. -1/2 ie the value of B.

Now substituting the value of B in the above equation:

12A + 6 A(-1/2) = A09

Or, 12A - 3 = 9A

Or, 12A - 9A = 3

Or, 3A = 3.

Or, A = 3/3 = 1.

So, the value of A is 1 and the value of B is -1/2. (Hence solved)

Here L.H.S = R.H.S.

Here, 12 x 1 + 6 x 1 x (-1/2) = 12 -3 = 9 which is equal to 9 X A ie 9 X 1 = 9.

Hence, proven.
