That is a perpendicular bisector
U had to take a pic of the work so we could see it
Subtract 13 from both sides.
-13
-7 = -20
-2x = -20
Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.
-2/-2 = 1
-20/-2 = 10
Your answer:
x = 10
I’m pretty sure it’s x>5 when add 4 to the other side and get 5 i’m just not sure about the sign
