Let 'x' be the first number 
      'y' be the other number 
----------------------------
-when added is 114
x + y = 114    ----equation 1
----------------------------
-when subtracted is 58
x - y = 58     ----equation 2
---------------------------
From equation 2
x - y = 58
x = y + 58    ----equation 2'
---------------------------
Substitute equation 2' to equation 1
x + y = 114
y + 58 + y = 114
y + y =  114 - 58
2y = 56
y = 28
--------------------------
Substitute y=28 to equation 2'
x = y + 58
x = 28 + 58
x = 86
------------------------
Therefore the two numbers are 28 and 86.
