The equation shown in the image is:

$|x - 1| = 2x + 1$

This is an absolute value equation, so we must break it down into two cases to solve:

Case 1: Positive case

In this case, we assume $x - 1 \geq 0$, so the absolute value can be removed directly: $x - 1 = 2x + 1$ Solve for $x$: $x - 1 = 2x + 1 \implies x - 2x = 1 + 1 \implies -x = 2 \implies x = -2$ Check if this solution satisfies the condition $x - 1 \geq 0$: $-2 - 1 = -3 \quad (\text{which is false})$ Thus, $x = -2$ is not a valid solution for this case.

Case 2: Negative case

In this case, we assume $x - 1 < 0$, so the absolute value must be negated: $-(x - 1) = 2x + 1 \implies -x + 1 = 2x + 1$ Solve for $x$: $1 - 1 = 2x + x \implies 0 = 3x \implies x = 0$ Check if this solution satisfies the condition $x - 1 < 0$: $0 - 1 = -1 \quad (\text{which is true})$ Thus, $x = 0$ is a valid solution.

Final Solution:

The only solution to the equation is $x = 0$.
