Question 1122969
---
 I came up with W=T+12 or T+12=W
---


No.
Neither of those.


<pre>
Wednesday was 12 degrees hotter than Tuesday. If it was t degrees on Tuesday, write an expression for the temperature on Wednesday.
Use either {{{12+t}}} or {{{t+12}}}.


Case level in using variables nearly always matters.  Decide if your variable is t, or T, stay consistent within the same problem.
