| SOLVING
COMPOUND INEQUALITIES |
|
Continuing to look at compound
inequalities, let’s solve for x when, 5 < -x < 10.
Note: The
coefficient of x is -1, thus you must think, “When
I multiply or divide an inequality by -1, the inequality
symbol changes direction.”
Step 1: 5 < -x < 10
-5 > x > -10
Read: “x” is greater than -10 and less
than -5. |
