2 x - 4 = 10
There actually isn't much to do other than plug into the formula. As with equations p merely represents whatever is within the absolute value bars. Thus, with this first one we have,
-10 + 2x - 4= 10
Now, it is nothing more than a fairly simple double inequality to solve thus let's do that.
-6 < 2 x < 14
-3 < x < 7
The interval notation for this solution is ( -3, 7 ) .
