Answer 2

Answer:

☑ let the rational numbers are x and y

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

and their difference is

x - y = 4

therefor x = 4 + y

☑ put x = 4 + y in equation (1)

(4+ y) + y = 30

4 + 2y = 30

2y = 30 - 4

y = 26 / 2

y = 13

☑ put y= 13 in equation (1)

x + y = 30

x + (13) = 30

x = 30 - 13

x = 17

The numbers are

$\boxed{\textbf{\large{13 and 17}}}$
