The sum of the two numbers x and y is 50.
→ The first equation is x + y = 50
The difference is 16.
→ The second equation is |x - y| = 16 (The bigger number is not known.)
→ And this gives x - y = 16 or x - y = -16.
x + y = 50, x - y = 16
→ x = 33, y = 17
x + y = 50, x - y = -16
→ x = 17, y = 33
The two numbers are 33 and 17.

Answer:
Let the two no. are = x and y.
Now,A.T.Q. =======
x+y = 50 _____ 1)
x-y = 16 _____ 2)
From eq. 2) , we get ====
x = y+16
Substitute the value of x in eq. 1) , we get======
y+16+y = 50
2y+16 = 50
2y = 34
y = 17.
Now, x = 17+16
x = 33.
