Question

What is one of the solutions to the following system of equations?

y2 + x2 = 53
y - x = 5 (2 points)


(-10, -5)


(-7, -2)


(7, 2)


(5, 10)

Answer 1

y^2 + x^2 = 53
y - x = 5

(-7,-2)

check...
-2^2 + (-7^2) = 53
4 + 49 = 53
53 = 53 (correct)

y - x = 5
-2 - (-7) = 5
-2 + 7 = 5
5 = 5 (correct)
