Answer:
It's division because to get x by itself, you need to divide both sides. X = 9
Step-by-step explanation:
6x = 54

Step-by-step explanation:
3x - 2y = 12
Substituting y = 9, we find:
Similarly, solving for point B (4, __) =B (4, 0)
Answer:
10
Step-by-step explanation:
If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.
The new equation would be 18 - 11 - 2 + 5.
Using PEMDAS, we get the answer of 10.
18 - 11 = 7
7 - 2 = 5
5 + 5 = 10
Hope this helps!
