Answer 3

To solve the inequality 2(2x + 6) - 3 ≤ 6x + 7, you'll need to simplify it and isolate the variable x. Here are the steps to do so:

1. Distribute the 2 on the left side of the inequality: 4x + 12 - 3 ≤ 6x + 7

2. Combine like terms on both sides of the inequality: 4x + 9 ≤ 6x + 7

3. Move the 4x term to the right side of the inequality by subtracting 4x from both sides: 9 ≤ 6x - 4x + 7

4. Simplify the right side: 9 ≤ 2x + 7

5. Move the 7 to the left side of the inequality by subtracting 7 from both sides: 9 - 7 ≤ 2x

6. Simplify the left side: 2 ≤ 2x

7. Finally, divide both sides by 2 to isolate x: 2/2 ≤ 2x/2 1 ≤ x

So the solution to the inequality is: x ≥ 1
