Can someone help me simplify (2n + 2) + (8 + 8)
emmasim [6.3K]

Answer:

7

Step-by-step explanation:

1. Lets Combine Like Terms. The only combineable terms are 8 and 8. So if we combine them they will equal 16. And we will have (2n+2)=16

2. Let's isolate the variable. We can do this by subtracting 2 from both sides. This will come out to 2n+14.

3. Let's further isolate the variable. We can do this by dividing both sides by two, which will finally come out to n=7
