Answer:

3n

Explanation:

We can see that the 3 gets distributed into the parentheses since there is a +21 on the right (3×7=21) so we also have to distribute the 3 to the n

The value of n in the equation 3(n + 7) = _ + 21 is 0.

Let's solve the equation:

3(n+7)=+21

We can solve the equation by distributing the terms on the left side, adding/subtracting to both sides, and dividing both sides by the same factor.

Steps to solve:

1. Distribute the terms on the left side:

3n+21=21

2. Add/subtract to both sides to isolate n:

3n=0

3. Divide both sides by the same factor to isolate n:

n= 3/0

n=0

Complete question below:

Solve for the value of n in the equation 3(n + 7) = _ + 21.
