Answer from: justhereforanswers13

X+y=57
x-y=33
make first one in x= form
x=-y+57
x-y=33
-y+57-y=33
-2y+57=33
-2y=-24

y=12

plug in to find x

x-y=33
x-12=33

x=45

Answer from: volleyballfun24

45 and 12!

Explanation below:

We have two equations!

x + y = 57
x - y = 33

This is a simple example of linear equations!

Let's use substitution in this case:

In one of the equations we need to get a variable by itself. Let's try the first one and try to get 'x' isolated by taking away y from the left side. That means we have: x = 57 - y.

Now let's plug this into the second equation, we have: (57 - y) - y = 33.

Let's release the parentheses and combine the negative y's to get: 57 - 2y = 33

Now take away 57 to try and isolate '2y', we get: -2y = -24.

Now divide by -2 to get y = 12.

Lastly plug 12 into any equation as y and solve for the x.

In the first one, we'd have x + 12 = 57.

That means x is 45!

We did it! Hope that helps!

Answer from: Quest

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
