Answer:
Lavania observed 39 fruit flies after 6 days of observation
Step-by-step explanation:
Let x be the number of fruit flies on the first day of Lavania's study.
After 6 days she had nine more than five times as many fruit flies as when she began the study.
Five times as many fruit flies as when she began the study = 5x
Nine more than five times as many fruit flies as when she began the study=5x+9
The expression to find the population of fruit flies Lavania observed after 6 days is 5x+9
If she observes 20 fruit flies on the first day of the study, then x=6, then

Answer:
8+3x
Step-by-step explanation:
Look at the first equation. If you add 3x to both sides of the equation, it becomes y-3x+3x=8+3x. Y-3x+3x is the same thing as just y, so the equation is really saying y=8+3x. Replace y in the other equation with 8+3x.
