No medal required or needed.
Better check the arith. that y ou've done so far.  Are you sure that 25 is negative?

mathmale · Answer

Why not try adding 7 to both sides of the equation first?

x=-3

arbyj · Answer

i got rid of the 18 bc i have to isolate the absolute value

mathmale · Answer

But if you do add 7 to both sides of the equation, your 18 becomes 25, right?  What next?

mathmale · Answer

You'll need to isolate the absolute value expression, as you said.
