|2z-7|=13 HELP absolute value is stressful

Question

anonymous · Answer

Since absolute value makes anything positive we know that if 2z-7 = -13, the absolute value would make it positive 13. If 2z-7 = 13 then the absolute value would keep the answer same, that is to say it will remain to be 13.

So here we have to cases, either 2z-7 = -13 or 2z - 7 = 13 but in either case the absolute value makes the answer positive which is 13. So now we solve for z in both cases to see the possible values that z could represent.

2z - 7 = -13
      2z = -6
        z = -3

OR

2z - 7 = 13
      2z = 20
        z = 10

Therefore, z = 10 or z = -3.
