Question

I need help on #17!!

Answer 1

you would distribute the 6 to the n and the 5. the equation would then be:
6n+30=66
you would then subtract 30 from both sides to get:
6n=36
divide each side by 6 to get:
n=6

Answer 2

Distribute first:

6•n= 6n

6•5=30

6n+30=66

Then it’s simple, subtract 30 from both sides to isolate your variable:

6n+30=66

   -30  -30

6n=36

Then divide both sides by six to get your answer:

N=6

Hope this helps!
