Answer :
Let the 2 numbers be x and y.
y = x + 30 ( as the difference between the two numbers is 30)
Sum of the two numbers = 100
=> x + y = 100
=> x + (x + 30) = 100 ( as y = x + 30 as shown above )
=> 2x = 70
=> x = 35
y = x + 30 = 65
Hope I helped! you may comment here if you have any further doubts and i will answer them :)

Let the two numbers be x and y.
According to your question ;
x + y = 100
x - y = 30
Thus. x = y + 30
Substituting the value of x,
y + 30 + y = 100
2y + 30 = 100
y = 70 / 2 = 35
thus, y = 35
Substituting the value of y,
x + y = 100
x + 35 = 100
x = 100 -35 = 65
x = 65.
thus, the two numbers are 65 and 35.

x + 35 = 100
x = 100 -35 = 65
x = 65.
thus, the two numbers are 65 and 35.
