<span>1. Martina is given to be 14 years older than Joey who is x years old. Hence, the age of Martina can be expressed as, x + 14
 2. If Joey's current age is x then in 5 years he will become x+5 years old.
 3. Martina's age will be her current age added with 5 making it, x+14+5 or x + 19.
4. The equation that would best represent the given scenario in this item is: x + 19 = 3(x + 5)
 5. From the given above, the value of x is equal to 2. This is Joey's current age.
 6. The current age of Martina is x + 14 which is equal to 16.</span>
