To solve the equation \( |x-1|=2x-1 \), we can break it down into two cases based on the definition of absolute value. **Case 1:** When \( x-1 \geq 0 \) (which simplifies to \( x \geq 1 \)), the equation becomes \( x-1=2x-1 \). Solving this gives \( x=0 \), which doesn't satisfy \( x \geq 1 \). **Case 2:** When \( x-1 < 0 \) (or \( x < 1 \)), the equation simplifies to \( -(x-1) = 2x - 1 \), leading to \( -x + 1 = 2x - 1 \). Solving this gives \( 3x = 2 \), or \( x = \frac{2}{3} \), which satisfies \( x < 1 \) and is thus a valid solution. So, the solution to \( |x-1|=2x-1 \) is \( x = \frac{2}{3} \).
