What?
twice older?
two times as old?

If Sarah is twice as old as John, and in three years the sum of their ages will be 33, then...

Sarah, 2j
John, j
%282j%2B3%29%2B%28j%2B3%29=33
-
3j%2B6=33
j%2B2=11
j=9--------John now
-
18--------Sarah now

---------
"once older" --> 1x older = 2 times as old.
twice older = 3 times as old.
==================
S = 3T
S+3 + 3*(T+3) = 33
Sub for S
3T+3 + 3T+9 = 33
6T + 12 = 33
6T = 21
T = 3.5
S = 10.5
---------------------
2 times older is NOT the same as 2 times as old.
-------------
PS 10 times smaller is meaningless, since 1 time smaller = 0
PS 10 times closer is meaningless, since 1 time closer = 0
