Question

8a-b2=24

And

8b+b2=56

Then

a+b=?

I need this answer

Answer 1

Given: Two equations 8a - b^2 = 24  and 8b + b^2 = 56

To find: The value of a + b?

Solution:

• Now we have given two equation:

            8a - b^2 = 24   ............(i)

            8b + b^2 = 56  ............(ii)

• From (i), we get:

            8a - 24 = b^2

• Putting this value of b^2 in (ii), we get:

            8b + 8a - 24 = 56

• Now solving this, we get:

            8b + 8a = 56 + 24

• Taking 8 common, we get:

            8(a + b) = 80

            a + b = 80/8

            a + b = 10

Answer:

               So the value of a + b is 10.
