Is it possible for AB=10, BC=2x + 5 and AC=5x, given that point B is the midpoint? Why or why not?

It's true whenever 2x + 5 = 10 and 10 + 2x + 5 = 5x. For what numbers does this happen?
x = 2.5 satisfies the first condition, and x = 5/3 satisfies the second. No number satisfies both.

wat is B the midpoint of? if it is of AC then it is not possible. coz AB should be equal in length of BC, 10=2x+5, x=2.5 but if AC=5*2.5= 12.5 does not tally with 20 which is of AB+BC=2*10=20
