Yep, stapel beat me to it, but that's how it's done . . .
Just for laughs and giggles, I tried to tackle
|2x-5|=4-|x-3|
and couldn't. I passed it off to Mrs. Fresh who is a math genius. She didn't do it algebraically, she just started plugging numbers in until she came up with the answer. She asked me to ask you how you can graph an equation with only one variable. Is there any more to the problem?
Also, I'm interested in how to go about solving the first posted problem algebraically. Is there a way, or is it strictly plug and solve? Thanks.
