-30-6x\leq 30
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
-6x\leq 30+30
Add 30 to both sides.
-6x\leq 60
Add 30 and 30 to get 60.
x\geq \frac{60}{-6}
Divide both sides by -6. Since -6 is negative, the inequality direction is changed.
x\geq -10
Divide 60 by -6 to get -10.
