Answer:

5

Step-by-step explanation:

1st: add 22 to both sides of the equation to get -50 = -10u

2nd: divide by negative ten in order to make u positive

-50 / -10 = 5

so... u=5

-72 = -10u + (-22)
22 = -10u
50 = -10u
——=——-
-10 = -10
5 = u

I think it’s right, if not the answer could be (-94/-10)=9.4 I apologize in advance if I’m wrong
