Solve for x -1>=-1+x

$- 1 \geq - 1 + x$

Rewrite so $x$ is on the left side of the inequality.

$- 1 + x \leq - 1$

Move all terms not containing $x$ to the right side of the inequality.

Add $1$ to both sides of the inequality.

$x \leq - 1 + 1$

Add $- 1$ and $1$ .

$x \leq 0$

The result can be shown in multiple forms.
