The sum is 21/25.
A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
2/5
This can be written as,
Multiply 5 on both the numerator and denominator.
= 2 x 5 / 5 x 5
= 10/25
Now,
10/25 + 11/25
= (10 + 11) / 25
= 21 / 25
Thus,
The sum is 21/25.

Step-by-step explanation:
multiply second equation by -2
-2 × (x+y) = 3➡ -2x - 2y = -6 now add up both equations
3x + 2y - 2x-2y = 5-6 ➡x = -1 (-2y eliminated +2y)
now use the value we found for x in the second equation to find the value of y
x + y = 3 we found x as -1
-1 +y = 3 ➡y = 4
