------
Equation::
14+x + 17+x = 169
--------
31 + 2x = 169
2x = 138
x = 69

Let +x+ = the number of years until
the sum of their ages will be +169+ years
----------------------
+%28+14+%2B+x+%29+%2B+%28+17+%2B+x+%29+=+169+
+31+%2B+2x+=+169+
+2x+=+138+
+x+=+69+
In 69 years the sum of their ages will be 169 years
check:
+%28+14+%2B+x+%29+%2B+%28+17+%2B+x+%29+=+169+
+%28+14+%2B+69+%29+%2B+%28+17+%2B+69+%29+=+169+
+83+%2B+86+=+169+
+169+=+169+
OK
