3x+1\leq \frac{20}{2}
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
3x+1\leq 10
Divide 20 by 2 to get 10.
3x\leq 10-1
Subtract 1 from both sides.
3x\leq 9
Subtract 1 from 10 to get 9.
x\leq \frac{9}{3}
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
x\leq 3
Divide 9 by 3 to get 3.
