Question

Tell whether the value is a solution of the inequality 5 − x < 8; x = −3

Answer 1

The value is not a solution of the inequality.

Explanation:

5 - x < 8

1. Substitute the variable, x, with -3: 5 - - 3 < 8

2. Use the KCC (keep,change,change) method to turn subtraction into addition: 5 + + 3 < 8

3. Add the numbers on left side of the inequality to get the answer: 8 < 8 - False statement - 8 is not less than 8.
