Step-by-step explanation:

To solve the equation x - 1 = 2, you need to isolate the variable x. Here's how you can do it step by step:

1. Start with the equation:

  x - 1 = 2

2. Add 1 to both sides of the equation to isolate x:

  x - 1 + 1 = 2 + 1

3. Simplify both sides of the equation:

  x = 3

So, the solution to the equation x - 1 = 2 is x = 3.

Answer:

x + 1x = 2 x^2 - 2x + 1 = 0 (x - 1)^2 = 0 x = 1
