Final answer:
To solve the given equation √(5-x) = 4, isolate x by squaring both sides and follow the steps: (5-x) = 16, -x = 11, x = -11.
Step-by-step explanation:
The given equation is √(5-x) = 4.
To solve for x, we need to isolate x by squaring both sides of the equation.
Squaring both sides, we get (5-x) = 4^2, which simplifies to 5-x = 16.
Subtracting 5 from both sides, we have -x = 16-5, leading to -x = 11.
Multiplying both sides by -1, we find that x = -11.
Therefore, the value of x is -11.
