X = - 5
x ^ 2 + y ^ 2 = 25
show work also

Step-by-step explanation:

Since x is equal to -5, you would need to substitute that value for x in the equation x^2 + y^2 = 25. So

-5^2 + y^2 = 25

(-5)*(-5) + y^2 = 25

25 + y^2 = 25

y^2 +25 - 25 = 25 - 25

y^2 = 0

y = 0

(x, y) = (-5, 0)

To check the answer

x^2 + y^2 = 25

-5^2 + 0^2 = 25

25 + 0 = 25

25 = 25

The answer should be correct, if not i am extremely sorry

Hope this helps!!!
