Answer:
[tex](\frac{u}{4} - 7)[/tex]
Step-by-step explanation:
We have to write the expression for the sequence of operations described in the question.
First of all, we have to divide u by 4.
Then we will get the expression of [tex]\frac{u}{4}[/tex].
Then we have to subtract 7 from the result obtained in the previous step.
Therefore, we will get the expression of [tex](\frac{u}{4} - 7)[/tex]. Hence, this is the final expression. (Answer)
