Each letter represents a digit.
 4z
 27
+x5
----
y14

Assume the units column: 
 z + 7 + 5 = 14
 z = 14 - 12
 z = 2
:
now we have
 42
 27
+x5
---
y14
:
The ten's column, we carry one from the units column
1 + 4 + 2 + x = 11
7 + x = 11
x = 11 - 7
x = 4
:
Now we have
 42
 27
+45
----
114
therefore:
y = 1
:
"what is the sum of x,y and z"
 4 + 1 + 2 = 7
