Answer:
Therefore, the solution to the inequality 2x + 1 ≤ 7 is x ≤ 3.
Explanation:
To solve the inequality 2x + 1 ≤ 7, we need to isolate the variable x on one side of the inequality sign.
First, we'll subtract 1 from both sides of the inequality:
2x + 1 - 1 ≤ 7 - 1
This simplifies to:
2x ≤ 6
Next, we'll divide both sides by 2:
2x/2 ≤ 6/2
This simplifies to:
x ≤ 3
