After having done this on paper:
We want to isolate the variable, and the first step is to subtract the 8.
Since the <em>n</em> is being multiplied by 3, and that = 8, we can multiply both sides by 3.
<em>n</em> = 24
Let me know if this helped you understand better.
Also, you can check this by substituting in 24 for <em>n</em>.

Answer:
Just took the test and got the correct answer :)))
Step-by-step explanation:
Look at the image down below!!
There is no solution to this system of equations; they will never spend the same amount.
The system of equations would be
We want one of the variables to have the same coefficient; we will make the coefficients of p be the same. To accomplish this, we will multiply the top equation by 3 and the bottom equation by 2:
When we subtract the equations to cancel p, we also cancel d in the process, leaving us
0 = 8
Since this is never true, there is no solution to the system.
