The answer is x = -2 and y = 2.

<u>Explanation</u>:

  • The first equation can be written as x - y = -4
  • The second equation can be written as 2x + y = -2

<u>step 1</u> :

Solving by elimination method to find the value of x and y,

x - y = -4

<u>2x + y = -2</u>

Why do rainforests have high biodiversity?
Ghella [55]

Answer:

Explanation:

Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate.

Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees.
