y = √25 − x2, y = 3

To find the solution to the given equation, we need to substitute the value of y into the equation y = √25 − x^2.

Given that y = 3, we can rewrite the equation as 3 = √25 − x^2.

To solve for x, we need to isolate the variable x.

First, let's square both sides of the equation to eliminate the square root:

(3)^2 = (√25 − x^2)^2

Simplifying, we get:

9 = 25 − x^2

Next, let's isolate the x^2 term by subtracting 25 from both sides:

9 - 25 = -x^2

Simplifying further, we have:

-16 = -x^2

To solve for x, we need to get rid of the negative sign. We can do this by multiplying both sides of the equation by -1:

-1 * -16 = -1 * -x^2

16 = x^2

Now, we can take the square root of both sides to solve for x:

√16 = √x^2

4 = x

Therefore, the solution to the equation y = √25 − x^2, y = 3 is x = 4.
