Final answer:

The solution to the equation sqrt((x-1)²) = 1 - x is x = 1.

Step-by-step explanation:

To solve the given equation, we start by simplifying the expression inside the square root. The square root of (x-1)² is the absolute value of (x-1). Therefore, we have |x-1| = 1 - x.

Now, we consider two cases:

1. When (x-1) is non-negative (x-1 ≥ 0):

In this case, |x-1| is equal to (x-1). So, the equation becomes (x-1) = 1 - x. Solving for x, we find x = 1.

2. When (x-1) is negative (x-1 < 0):

In this case, |x-1| is equal to -(x-1). So, the equation becomes -(x-1) = 1 - x. Solving for x, we find x = 1.

Since both cases lead to the same solution, x = 1, we conclude that this is the solution to the given equation. It's important to note the application of absolute value to consider both positive and negative cases.

Answer:

The value of x is 1

Step-by-step explanation:

√(x – 1)² = 1 – x

x – 1 = 1 – x

x – 1 + 1 + x = 1 + 1 – x + x

2x = 2

2x/2 = 2/2

x = 1

Thus, The value of x is 1
