The first group of organisms to colonize an area would be the Centaurea maculosa, an example of pioneer species. Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems. Hope this answers the question.

x = -10

Step-by-step explanation:

distributive property

(2·x) + (2·3) = x - 4

2x + 6 = x - 4

subtract x to both sides

x + 6 = -4

subtract 6 to both sides

x = -10
