Question
Solve each compound inequality for x. See the example below. To solve x - 6 6 3x 6 2x + 5, notice that this inequality contains a variable not only in the middle but also on the left and the right. When this occurs, we solve by rewriting the inequality using the word and.x - 6 6 3x and 3x 6 2x + 5-6 6 2x and x 6 5-3 6 xx 7 -3 and x 6 5x + 3 6 2x + 1 6 4x + 6
Solution
The first step in solving 2.5 problem number 86 trying to solve the problem we have to refer to the textbook question: Solve each compound inequality for x. See the example below. To solve x - 6 6 3x 6 2x + 5, notice that this inequality contains a variable not only in the middle but also on the left and the right. When this occurs, we solve by rewriting the inequality using the word and.x - 6 6 3x and 3x 6 2x + 5-6 6 2x and x 6 5-3 6 xx 7 -3 and x 6 5x + 3 6 2x + 1 6 4x + 6
From the textbook chapter Compound Inequalities you will find a few key concepts needed to solve this.
