Also, remember that if the value inside the absolute value bars is negative, it converts to positive.  So to solve an equation like |x+3| = 5, you really have to solve TWO equations:  x+3=5 or x+3= -5.\n\nIf the absolute value portion of the equation is not by itself, you must make it so first.  For example:\n\n|2x + 1| + 3x = 5       First subtract 3x from both sides:\n\n|2x + 1| = 5 - 3x      Then split into 2 equations:\n\n2x+1=5-3x  or 2x+1 = - (5-3x) [which would be -5 + 3x]\n\nsolve each equation to get the 2 values of x
