Homework Statement
I have this equation
|2x+7| - |6-3x| = 8.
The step I did is to replace the || with () and then solve the equation
2x+7-6+3x = 8
X = 7/5
But how do a go about solving for the second solution?
With one absolute value I would
|2x + 7| = 8
2x + 7 = +-8
2x = -7 +-8
X = -15/2, x = ½
But I can’t see how to solve the first equation for the second solution.
