Answer 1

Answer:

If a3 + b3 = 9 Equation 1

& a + b = 3 Equation 2

Now we use trial and error method to find answer

Lets assume value of a & b is 1 each

Then do we get desired result

No we do not get 9 when we assume value as 1

Now we assume value as 1.5 for a & b each

Do we get desired result?

Yes!! when we substitute value of a & b as 1.5 in equation 1 we get answer as 9

Yes!! when we substitute value of a & b as 1.5 in equation 2 we get answer as 3

So value of a = 1.5 & b = 1.5
