u=4

Explanation:

First, since there are fractions in this question, we can find the common denominator and group the fractions together, which is easier for us to do the question.

5=u+65+5u26
5=(u+6)656+(5u2)565
5=u6+6630+5u52530
5=6u+36+25u1030

Then, we can multiply by 30 on both sides to eliminate the denominator.

530=6u+36+25u103030
150=26+31u
124=31u
u=12431=4

Here is the answer. Hope this can help you :)
