Let the two numbers be = x and y
Given:
x + y = 70 ...(1)
x - y = 60 ....(2)
(1) + (2)
=》 x + y + x - y = 70 + 60
=》 2x = 130
=》 x = 65
y = 70 - 65 = 5
That's your answer.

Here is your answer:
Let the two numbers be x and y.
Sum of the two numbers is 70.
x+y=70......(eqn.1)
Their difference is 60.
x-y=60.......(eqn.2)
Adding eqn.1 and 2
x + y = 70
x - y = 60
___________
2x = 130
x = 130/2
x = 65
Substituting x=65 in eqn.1
x+y=70
65+y=70
y=70-65
y=5
The numbers are 65 and 5.
Hope it helps.☺☺
