Question

find the solution or solution set for: |2z-7|=13

Answer 1

Well when you solve with absolute value you will have two different equations:
2z-7=13 and 2z-7=-13
No just solve for z on both.

Answer 2

Do I add 7 on both sides with the 2?

Answer 3

Yes you will add 7 to both sides to get 2z=20 and 2z=-6.
And then what will you do?

Answer 4

Oh okay thanks! I get it now. & then I divide 2 by both sides which will make my 2's cross out and will get me 10,-3 :)

Answer 5

Yep!
