Final answer:
To solve the equation √x-1-5=2-8, we need to isolate x on one side of the equation. A valid solution for x is 25.
Step-by-step explanation:
To solve the equation √x-1-5=2-8, we need to isolate x on one side of the equation. Let's follow the steps to solve it:
- Add 5 to both sides of the equation: √x-1 = -6
- Add 1 to both sides of the equation: √x = -6 + 1 = -5
- Square both sides of the equation to eliminate the square root: (√x)^2 = (-5)^2
- Simplify: x = 25
