o wow your asking me do do this well i can so i will show you.
[x]+5=11
you will first subtract 5 from 11 and 5 so it would look like this---[x]=6
so the answer would be 6 or -6 because any number in a absolute value sybol is always positive.

What's your question? To solve an absolute value inequality, knowledge of absolute values and solving inequalities are necessary. Absolute value inequalities can have one or two variables.
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
Absolute Value means the distance from 0, and so you should solve the equation with the number inside the Absolute Value lines as a positive and then solve again as a negative.
To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.
