Easiest way to solve this is to try plugging in the values from the table into the equations
Let’s try y = x + 4
The first coordinates from the table says
(-9 , -5 )
-5 = -9 + 4
-5 = -5
They match, so y = x + 4 is the right answer. You can try plugging in the other variables if your still uncertain
Answer:
n = 4
Step-by-step explanation:
3 + 4n + n = 2n +15
3 + 5n = 2n + 15
5n - 2n = 15 - 3
3n = 12
n = 12 / 3
= <u>4</u>
