Step 3: Simplify
n = 4/7
Answer:
(3,2)
Step-by-step explanation:
Let's solve this via elimination method:

By subtracting equation 2 from equation one we obtain:

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

Therefore the solution for the system of equations is:
x=3 and y = 2 as an ordered pair we have (3,2)
Explanation:
AB=7
AC=9
You are looking for R
7+9=16
So R is 16
Answer:
The answer is c: N + 13 = 20
