Let, the 2 numbers be 'a' and 'b'.
Given,
a + b = 20 ---- equation 1
a - b = 10
a = 10 + b ----- equation 2
Substitute equation 2 in 1
a + b = 20
10 + b + b = 20
10 + 2b = 20
2b = 10
b = 10/2
b = 5 ----- equation 3
substitute equation 3 in 1
a + b = 20
a + 5 = 20
a = 20 - 5
a = 15
Therefore, the two numbers are 5 and 15.
