Answer:

x=12

Step-by-step explanation:

Midpoint B of segment AC creates both equal segments AB and BC. The midpoint halves out AC therefore AB=BC

The equation would look like 2x-5=x+7 where you want to isolate x fully. First you want to add 5 on both sides of the equation so that you get 2x=x+12. Next subtract x from both sides of the equation to then get x=12.
