-z+3\leq -7
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
-z\leq -7-3
Subtract 3 from both sides.
-z\leq -10
Subtract 3 from -7 to get -10.
z\geq \frac{-10}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
z\geq 10
Fraction \frac{-10}{-1} can be simplified to 10 by removing the negative sign from both the numerator and the denominator.
