Their is one guy catching fish in a lake. While catching fish their are flamingos flying over the lake. The flamingo flying in front screams to the guy catching fish - All of us, plus all of us, plus the half of us, plus a quarter of us, plus you cathing the fish is 100.
How many flamingos flew over the lake???😕

I'll give up after figuring out i needs to appear in the solution.
Never paid much attention to maths lectures by that point.

x+y=10 and x*y=40
Rearranging the first:
y=10-x
Substituting into the second:
x*(10-x)=40
Simplifying and leaving zero on one side:
-1*x^2 + 10*x - 40 = 0
A quick check of b^2 - 4*a*c gives a negative answer meaning on real solutions to this quadratic (square root of a negative number).
x= 5 (+-) 3.8729*i
Therefore there are no real numbers which satisfy your criteria.
