Maluwa solves the inequality 3x+9≥6. Which statement explains the steps she uses to find the solution set of the inequality?

1 answer

Maluwa solves the inequality 3x + 9 ≥ 6 by following these steps:

1. She subtracts 9 from both sides of the inequality: 3x + 9 - 9 ≥ 6 - 9
This simplifies to: 3x ≥ -3.

2. Then, she divides both sides of the inequality by 3: (3x)/3 ≥ (-3)/3
This simplifies to: x ≥ -1.

3. Therefore, the solution set for the inequality is x ≥ -1.
