Question
Solve the equation or inequality. Write the solution set to each inequality in interval notation.a. $|x|=7$b. $|x|<7$c. $|x|>7$
Step 1
Therefore, if $|x|=7$, it means that $x$ is 7 units away from zero. This can be in either direction, so $x$ can be either 7 or -7. Therefore, the solution to the equation $|x|=7$ is $x=7$ or $x=-7$. Show more…
