-1\geq 1-2n
Subtract 5 from 6 to get 1.
1-2n\leq -1
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
-2n\leq -1-1
Subtract 1 from both sides.
-2n\leq -2
Subtract 1 from -1 to get -2.
n\geq \frac{-2}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
n\geq 1
Divide -2 by -2 to get 1.
