Answer:11, 76

Step-by-step explanation:Let the two numbers be x and y.

According to the given conditions:

x + y = 87…..(1)

x – y = 65….(2)

Adding equations (1) & (2)

x + y = 87

x – y = 65

__________

2x = 152

x = 152/2

x = 76

Plug x = 76 in equation (1)

76 + y = 87

y = 87 – 76

y = 11

Thus the two numbers are 11 and 76.
