Thank you for the opportunity to help you with your question!

Hi! So what we need to do is set up two separate equations. 


1. x -72.5 = 4

2. x-72.5= -4


For x-72.5= 4, add 72.5 to both sides to solve for x. So 4+72.5= 76.5


For x-72.5= -4, add 4 to both sides. This gives you x-68.5= 0. Then once we solve for x we get 68.5. 

So the answer is 68.5 and 76.5 


Let me know if you have any questions! Thanks!
