Answer:

The solution is d = 3 and e = -1

Step-by-step explanation:

To solve using the substitution method, we need to first solve the second equation for d.

d - e = 4

d = e + 4

Now that we have the value of d, we can put it in for d in the first equation and solve for e.

d + e = 2

(e + 4) + e = 2

2e + 4 = 2

2e = -2

e = -1

Now that we have this value, we can plug it into the original equation and find d.

d + e = 2

d + -1 = 2

d = 3

Answer:

C) It helps reduce carbon dioxide emissions

Step-by-step explanation:

Methane being a vital greenhouse gas and produces 84 times more heat than carbon dioxide, its concentration varies across the seasons and can remain in the atmosphere for a period of 12 years.

Methane has the ability to stay in the atmosphere without the oxygen for a longer duration.

The gas can produce water vapor through the chemical reaction when it reaches the mesosphere and is most likely to produce clouds.

<u>The environmental benefits of this gas is that it can produce energy by mass and are more refined than oil and creates less pollution and pollutants.</u>
