Solve inequalities by adding or subtracting quick check test

Answer 1

To solve inequalities by adding or subtracting, you simply perform the same operation to both sides of the inequality. Here is a quick check test to ensure you understand this concept:

1. Solve the following inequality by adding or subtracting:
2x + 5 < 11

First, subtract 5 from both sides:
2x < 6

Then, divide both sides by 2:
x < 3

So the solution to the inequality is x < 3.

2. Solve the following inequality by adding or subtracting:
3y - 7 ≥ 14

First, add 7 to both sides:
3y ≥ 21

Then, divide both sides by 3:
y ≥ 7

So the solution to the inequality is y ≥ 7.

If you were able to solve these inequalities correctly using addition and subtraction, then you have a good understanding of this concept. Keep practicing to further improve your skills in solving inequalities.
