Answer: 6

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6-3*n-(-12)=0

Step 1 :

Pulling out like terms :

Pull out like factors :

18 - 3n = -3 • (n - 6)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : -3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : n-6 = 0

Add 6 to both sides of the equation :

n = 6

One solution was found :

n = 6

Answer: n = 6

Step-by-step explanation:

6 - 3n = -12

Collect like terms

-3n = -12-6

-3n = -18

Divide both side by -3

-3n/-3 = -18/-3

n = 6

mestny [16]

Answer:

credits to the two revenue accounts

Explanation:

The journal entry above is focusing on "two revenue accounts" and these are "Fees Earned" and "Rent Revenue."

Remember that "Fees Earned" is part of the revenue section in the Income Statement. It is the amount of money earned for services provided such as auditing fees or consulting fees.

An increase in revenue is being credited when it comes to journal entries. So, this means that "credits to the two revenue accounts" have to be made.

So, this explains the answer.
