B is the midpoint of AC. AB = 2x - 8 and BC = x + 14. Solve for AC

Question

Solving for miss length of line

Answer 1

A----------B----------C

2x-8 x+14

Since B is the midpoint of AC, then AB = BC:

AB = BC

2x - 8 = x + 14

Solve for x. Once you have x, AC = 2x - 8. Check that BC = x + 14 equals the same value as AB.
