: how would i go about solving this and what does the two lines with the x in the middle mean
The lines are the symbol for ABSOLUTE VALUE. An absolute value is a number's distance from zero on a number line.
|-2|= 2 and |2|=2 see?
In the above problem, solve for X. If X is negative, make it positive. If it is positive KEEP it positive.
