Steps:
So let's focus on the first half of this compound inequality: 7x - 9 < 12 . Firstly, add 9 to both sides of the inequality:
7x < 21
Next, divide both sides by 7 and your first answer is x < 3.
Next, we will focus on the second half of the inequality: 1/4x + 8 > 11 . Firstly, subtract 8 on both sides of the inequality:
1/4x > 3
Next, multiply both sides by 4 and your second answer will be x > 12.
Answer:
Putting it together, your final answers are x < 3 OR x > 12.
