Here's your answer...❤❤

Let the two numbers be x and y.

ATQ (According To Question)

Sum of two numbers is 30

x + y = 30......(1)

Sum of that two numbers is 4

x - y = 4......(2)

On solving equation (1) and (2)...

x + y = 30

x - y = 4

- + -

2y = 26

y = 26/2

y = 13

Putting y = 13

x + y = 30

x + 13 = 30

x = 30 - 13

x = 17

Ans. The two numbers are 17 and 13.
