Answer:
a ≠ 2
Step-by-step explanation:
Given
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that a cannot be, that is
- 3a + 6 = 0 ( subtract 6 from both sides )
- 3a = - 6 ( divide both sides by - 3 )
a = 2 ← excluded value

The equation 4n + 7 = 55 is used to find the value of n.
The value of n is founded as n=12.
<u>Step-by-step explanation</u>:
Let 'n' be the number of people seated at each of the 4 large tables.
- The number of guests seated in 4 large tables = 4n
- The number of guests seated in smaller table = 7
- Total number of guests = 55
Total guests = guests in larger table + guests in small table.
The equation framed is 55 = 4n + 7
⇒ 4n = 55-7
⇒ 4n = 48
⇒ n = 12
