3. Five tickets are sold at P 600.00
The price for one ticket =
= 120
One ticket is sold for P 120.00.

Answer: a = -3
Explanations:
The given equation is:
This can be re-written as:
Collect like terms:
Cross multiply:
To verify if the solution is correct, substitute a = -3 into the question given. If the Right Hand Side equals the Left Hand Side, then the solution is correct.
Since the Left Hand Side = Right Hand Side = 7, the solution a = -3 is correct
Answer:
