Answer: b ≤ 2
Work Shown:
3b+2 ≤ 8
3b+2-2 ≤ 8-2
3b ≤ 6
3b/3 ≤ 6/3
b ≤ 2
Explanation: In the 2nd step, I subtracted 2 from both sides. In step 4, I divided both sides by 3. The inequality sign stays the same. It would flip if we multiplied or divided both sides by a negative number.
If you want to graph this on a number line, then plot a closed filled in circle at 2. Then shade to the left. This visually represents numbers that are 2 or smaller.
