I've to solve the following absolute value equation 8w7=72.
I solved the equation and the answers I got were 2 and 16. However the problem is that when I'm checking the equation with the answers it's not coming right.
I.E.
8167=72
89 = 72
8(9)= 72
72 = 72 (which is right)
827=72
89 = 72
8 (9) =  72
72 = 72 (its coming wrong)
Thus is the second equation right and am I solving it in the right way?

Sorry! I got it now! I was solving it the wrong way! silly me! :p:) Sorry to bother you!

Nice work! Both of your solutions are correct. Thanks for rechecking (and doing) your own work! It makes our job easier.
