Close. Let's see where you went wrong though.

 

-3u=15

 

divide by -3

 

-3u=15

 -3    -3

 

u=-5

 

So the answer is -5. Good try though!

-3u = +15

 

Find the value of u.

 

The value of u is -5. A negative multiplied by a negative is a positive. If the answer was -15, then the value of u would be +5, since a negative multiplied by a positive (vice versa) equals to a negative.

 

Hopefully that helps.
