Answer 2

Since there area absolute value signs in enclosing both sides of the equal sign, it means that either 2x-7 or 2x+6 could be negative.

So what if 2x-7 had a negative answer? If you take away the abs value signs you would have a -1 that you would need to deal with:

-1(2x+7)=2x+6

-2x-7=2x+6

1=4x

1/4=x

If you assumed that 2x-6 was the negative you would get the following:

2x-7=-2x-6

4x=1

x=1/4

Assuming 2x-7 and 2x+6 are either both pos or neg won't work because if you try to solve for x you get 0=1.

Hope this helps.
