Find the value of two numbers if their sum is 130 and their difference is 28

Step-by-step explanation:

let the two numbers are x and y

x+y = 130

x-y=28

on adding both the above equations

x+y+x-y = 130+28

2x = 158

x = 79

putting the value of x in any of the equation

79+y = 130

y = 130 - 79

y = 51

79 and 51

They add to get 130 and subtract to get 28
