Answer:

x = 3

Step-by-step explanation:

Given that,

BC = 24 ft

AC = 2x+1

BA = 7x-4

We need to find the value of x. It can be consider that A is a point that lies on BC. It means,

BC = AB + AC

Putting all the values, we get :

24 = 7x-4+2x+1

Solving above equation, we egt :

24-1+4=7x+2x

27=9x

x = 3
