Here is one way to do the steps
T = 3u/e
Te = 3u
3u = Te
u = Te/3
In the second step, I multiplied both sides by 'e'.
Afterwards, I swapped both sides so that the variable 'u' was on the left side.
Lastly, divide both sides by 3 to isolate the variable 'u' entirely.
The basic idea is to follow PEMDAS in reverse. So for instance, we divided both sides by 3 to undo the multiplication of 3 to the variable 'u'.
The "Te" refers to variable "T" multiplied with variable "e".

A note to help you with your studies of mathematics....
Technically, the question can't be answered; we can't solve for "U", because "U" does not appear in the given equation.
It is not at all uncommon to have two different variables like r and R in the same problem. So in a problem involving both "u" and "U", it must be assumed that those represent different numbers, unless that statement of the problem specifically says they are the same.
