Answer:

67.2 and 94.1

Step-by-step explanation:

Let x represent one number and y represent the other

their sum is

x + y = 161.3 and the difference

x - y = 27.9 now add two equations

x + y + x - y = 161.3 + 27.9

2x = 188.2 divide both sides by 2

x = 94.1 to find the other number subtract this from 161.3

y = 161.3 - 94.1

y = 67.2
