Verified step by step guidance

Start with the given inequality: $\left|10x - 4\right| - 2 > -8$.

Isolate the absolute value expression by adding 2 to both sides: $\left|10x - 4\right| > -8 + 2$.

Simplify the right side: $\left|10x - 4\right| > -6$.

Recall that the absolute value of any expression is always greater than or equal to 0, so $\left|10x - 4\right|$ is always non-negative and thus always greater than -6.

Since the inequality $\left|10x - 4\right| > -6$ is true for all real numbers, the solution set is all real numbers. To graph this, shade the entire number line.
