Remember that an absolute value represents a distance from zero, so if we are given two solutions and asked to write an absolute value equation, we'll somehow need to figure out what is the starting place (like zero) and how far should we be traveling in each direction to arrive at those solutions. The distance traveled has to be the same, so we will need to find the mid-value between the two given solutions and put that in absolute value marks with x, and then the distance traveled will be what the absolute value is equal to.
