    then again you could plug in the two numbers and see if they both work that way you don't have to actually solve anything lets solve it first

    the first step is to remove the absolute value signs, and write two separate equations \[|3x+12|=18\] becomes \[3x+12=18\] or \[3x+12=-18\]

    you have to solve both separately but the steps for both are the same a) subtract \(12\) from both sides, then b) divide both sides by \(3\)
