Solve this system of linear equations. Separate the x- and y-values with a comma.
18x - 7y = -17
3x - 3y = -12

18x-7y=17

18x=-17+7y

x=-17+7y/18

Step-by-step explanation:

answer=-16.6111111111

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.
