So you have many ordered pairs here that look like (x , y)
So you take each one, for example (84,12) and plug it into that equation you have
<span>y=7x</span>
(84 , 12) means (x = 84, y = 12 ) so we plug those in
<span>12=7(84)</span><span>
Does that come out true? if it doe...we have a solution..if not...obviously not :)</span>

Answer:
The answer is
and 
Step-by-step explanation:
Given:
-4x-2y=14
-10x+7y=-24
Now, to solve it by elimination:
......(1)
......(2)
So, we multiply the equation (1) by 7 we get:

And, we multiply the equation (2) by 2 we get:

Now, adding both the new equations:




<em>Dividing both the sides by -8 we get:</em>

Now, putting the value of
in equation (1):




<em>Subtracting both sides by 25 we get:</em>

<em>Dividing both sides by -2 we get:</em>

Therefore, the answer is
and
