Solve the compound inequality. Express your answer using inequality signs, and then write your answer using interval notation.
Finally, we check our solution. We can do this by substituting a number from the interval into the original inequality. For example, if we choose
Step 1 :First, we need to solve the compound inequality. We can do this by breaking it down into two separate inequalities:
Step 2 :Let's start with the first inequality
Step 3 :Next, we divide both sides of the inequality by 7 to isolate
Step 4 :Now, let's solve the second inequality
Step 5 :Next, we divide both sides of the inequality by 7 to isolate
Step 6 :So, the solution to the compound inequality is
Step 7 :Finally, we check our solution. We can do this by substituting a number from the interval into the original inequality. For example, if we choose
