Make one of the variables drop out.
I'd go for the y since it's easiest in this problem.
Time the top equation by -1.
This changes the system to:
Add the equations.
The equation would be:
Or simply:
Solve for x by dividing.
Then, plug x into one of the original equations to find y.
I'm going to use the first one since the numbers are smaller, but you CAN use either.
Put these into an ordered pair.
(0,1)
That is your answer.
Hope this helped!

<em>26.</em>
Step-by-step explanation:
To figure out the missing side of a right triangle, we will use the Pythagorean theorem. This is...
With this Pythagorean theorem, a and b will always be the legs and the c will always be the hypotenuse, no matter what. Now knowing this, we can plug the legs into the equation.
Add the legs together.
Now, since c is squared we will have to find the square root of 676.
= <u>26</u>
