Question 1196256
<font color=black size=3>
Here is one way to do the steps
T = 3u/e
Te = 3u
3u = Te
<font color=red>u = Te/3</font>


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".
