-3(n+5)=12 what is n?

-3(n+5)=12

First, use the distributive property.

-3*n=-3n

-3*5=-15

So your new equation is...

-3n-15=12

Next, add 15 to each side to put n on one side.

-15+15=0

12+15=27

You now have...

-3n=27

Finally, divide each side by -3 to make -3n into n.

-3n/-3=n

27/-3=-9

In conclusion...

n=-9

-3(n+5)=12 n must be -9 because -9+5=-4 then -4*-3=12

3x4=12

-9+5=-4

-3x-4=12
