Do what it says; solve one of them for y. I'll do the first one:
Now that we know what y is, we can substitute that into the other equation:
Now distribute:
And simplify:
Now that we know what x is, just put that value into either equation to find y, I'll do the first one since we already solved for y:
And simplify:
Now just put the values into a coordinate pair:

Step-by-step explanation:
Answer: 6.40 = c
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 4^2 = c^2
25 + 16 = c^2
41 = c^2
____
_/ 41 = c
6.40 = c
