18+34b\geq 86
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
34b\geq 86-18
Subtract 18 from both sides.
34b\geq 68
Subtract 18 from 86 to get 68.
b\geq \frac{68}{34}
Divide both sides by 34. Since 34 is positive, the inequality direction remains the same.
b\geq 2
Divide 68 by 34 to get 2.
