You can put this solution on YOUR website!
Let +n+ = number of years ago
Cameron's age was 3 times Holly's age
+58+-+n+ = Cameron's age +n+ yrs ago
+28+-+n+ = Holly's age +n+ yrs ago
------------------------------------
Given:
+58+-+n+=+3%2A%28+28+-+n+%29+
+58+-+n+=+84+-+3n+
+2n+=+26+
+n+=+13+
13 yrs ago, Cameron's age was 3 times Holly's age
----------------
check:
13 yrs ago, Cameron's age was:
+58+-+13+=+45+
13 yrs ago, Holly's age was:
+28+-+13+=+15+
and
+45+=+3%2A15+
OK
