Question

I am thinking of two numbers.What will my number be if their sum is 5 and their product is 6?

Answer 1

2 and 3 just sort of popped into my mind.

Answer 2

Let x= first unknown
y= second unknown

X+Y = 5 equation 1
(X)*(Y) = 6 equation 2

FROM EQUATION 2
Y= 6/X ( substitute to equation 1)

SO Equation 1
X + (6/X) = 5
X=2
Substitute (X) to ant equation)
Y= 5-2 = 3
SO X= 2 AND Y= 3

Answer 3

If you are going to give a detailed solution, then you should not gloss over the critical part of your solution:

SO Equation 1
X + (6/X) = 5
X=2

or else you might just as well state the obvious solution at the beginning.

Answer 4

3 and 2
