Question

Solve for u. I need a little help.

Answer 1

value of 'u'= -54

Explanation:

`30 = -(5)/(9)u`

To eliminate any number , we always do opposite operation

To remove denominator 9, we multiply both sides by 9

`30*9 = -(5)/(9)*9*u`

270 = -5u

To remove -5 we divide by -5 on both sides

`(270)/(-5) = (-5u)/(-5)`

-54= u

So value of u= -54
