Final answer:
Emilia scored 7 points in the game.
Step-by-step explanation:
Let's assume that Emilia scored x points in the game.
According to the problem, Sarah scored 3 less than 5 times as many points as Emilia. So, Sarah's score can be represented as (5x - 3).
To find the total number of points Emilia and Sarah scored together, we add Emilia's score and Sarah's score: x + (5x - 3). This sum is equal to 39 points.
Combining like terms, we get 6x - 3 = 39. Adding 3 to both sides, we have 6x = 42. Dividing both sides by 6, we find that Emilia scored x = 7 points in the game.
