Let the two numbers are x and y.
As per statement, the sum of two numbers is 30. Accordingly
x + y = 30…Eq..1
And their difference is 6.
x - y = 6
x = 6 + y…Eq .2
Substituting the value of x from Eq..2 to Eq.1
x + y = 30
6 + y + y = 30
6 + 2y = 30
2y = 30 - 6
2y = 24
y = 24/2
y = 12
Substituting the value of y in Eq..1
x + 12 = 30
x = 30 - 12
x = 18
The two numbers are x = 18 and y = 12.
Answer: The two numbers are 18 and 12.
