Question

Solve for x: −7 < x − 1 < 8

6 < x < 9
−6 > x > 9
6 > x > −9
−6 < x < 9

Answer 1

-6 < x < 9

To solve this inequality, you can add 1 to both sides of the inequality to get:

−7 + 1 < x − 1 + 1 < 8 + 1

-6 < x < 9

This inequality is a compound inequality, which is made up of two separate inequalities joined by the word "and".
