What is the first step to solve for n

in the following equation?
3n - 7 = 30

n = 37/3

n = 12  1/3

Step-by-step explanation:

Hi there !

3n - 7 = 30

3n = 30 + 7

3n = 37

n = 37/3

n = 12  1/3

Good luck !

final answer is : )

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
