Question

12A
+6AB
=A09
FindA=,B=

Answer 1

for this 12A+ 6 AB = WE KNOW THAT THERE ARE THREE A WHICH ARE EQUAL TO EACH OTHER . SO IF WE TAKE A= 8 , 8+B = 9 AND 2+8 =1 0 so this is correct and b = 8+B=9 , B= 9-8=1

Answer 2

Answer:

Step-by-step explanation:

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.
