Answer

no solution

Work Step by Step

$\bf{\text{Solution Outline:}}$ To solve the given inequality, $ |7-2x|\le-9 ,$ use the definition of absolute value to analyze the given inequality. $\bf{\text{Solution Details:}}$ The absolute value of $x$, given by $|x|,$ is the distance of $x$ from $0,$ and hence is always a nonnegative number. Therefore, for any $x,$ the expression at the left, $ |7-2x| ,$ is nonnegative. This is NEVER less than or equal to the negative expression at the right. Hence, there is $\text{ no solution .}$
