12\leq 18+x
Multiply both sides of the equation by 3. Since 3 is positive, the inequality direction remains the same.
18+x\geq 12
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
x\geq 12-18
Subtract 18 from both sides.
x\geq -6
Subtract 18 from 12 to get -6.
