Answer:
value of 'u'= -54
Step-by-step explanation:
[tex]30 = -\frac{5}{9}u[/tex]
To eliminate any number , we always do opposite operation
To remove denominator 9, we multiply both sides by 9
[tex]30*9 = -\frac{5}{9}*9*u[/tex]
270 = -5u
To remove -5 we divide by -5 on both sides
[tex]\frac{270}{-5} = \frac{-5u}{-5}[/tex]
-54= u
So value of u= -54
