Answer:3
Step-by-step explanation:
Do you have a graph on that
Well, It would be hard to write out the formula and everything here so I wrote it out for you! Work shown!
A=6
2*6=12
12-8=4
B=6
3*6=18
18-8=10

First, replace the numerator with the parentheses.
Second, multiply both sides by 3.
Third, multiply 2 × 3 to get 6.
Fourth, take away 15 from each side.
Fifth, simplify -6 - 15 to get -21.

Answer:
n = -21
