Thanks for your questions. Your problem was –

If a – b = 3 and a2 – b2 = 25, then find the sum of both the variables ‘a’ and ‘b’

Correct answer: d

Let’s we see how?

I’m trying to solve your problem and explain in details.  now let’s see –

Your question’s details Explanation:

We know the standard algebraic formula for (a)2 – (b)2
(a)2 – (b)2 = (a + b) (a – b)
Now, according to the data given in the question, a – b = 3 and a2 – b2 = 25.
Substituting these values in above equation, we get,
25 = (a + b) (3)
∴ (a + b) = 25/3
∴ a + b = 8.3333
Hence, the correct answer is option d.
