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>
<u>3x = -6</u>
<u>step 2</u> :
x = -6/3 = -2
The value of x is x = -2
<u>step 3</u> :
Substitute x = -2 in any of the given equations.
⇒ y = x + 4
⇒ y = -2 + 4
⇒ y = 2
It might affect your life because you might not be able to purchase something that you know exists in countries with a free market because your country that has a command economic system doesn't produce it and regulates what can and cannot be imported. Very often such countries also have high tariffs so even if imported, those goods are often expensive.

Answer:
A tidal bore is a rare natural phenomenon in which an incoming tide creates a wave of water that travels up along a river or a narrow bay causing water to flow against the river's current. Tidal bores occur in relatively few locations worldwide.
Tidal level in the Chesapeake Bay is not affected by moon phases. During the full and new moons, the high tidal level should be the highest. During 1st and 3rd quarter moons, the high tides should be the lowest.

Answer:
A stream in a bedrock valley located 5000 feet above ultimate base level that is draining a mountainous region in the headwater of a stream system would have a _____.
high gradient, and a narrow and shallow channel with no floodplain
Explanation:
A bedrock valley has no alluvium mantling the bedrock over which it flows. Alluvium (consists of sand, gravel, silt, clay, and gravel, as well as other organic matters) mantlings or coverings are usually developed in the lower part of the river with the formation of floodplains and deltas. They may also be deposited at lakes or river banks. Headwater streams deliver nutrients and other organic materials (e.g. fallen leaves) to downstream regions to sustain downstream aquatic life.
