What is the Answer I need the real answer I’m stuck on it

multiply both sides by 3x + 7

Step-by-step explanation:

this will eliminate the fraction in the equation and therefore make it easier to isolate x

hope this helps :)

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.
