Question

A, B, and C are collinear B is between A and C.
If AB = x+4, BC = 2x-10, and AC =2x+1. then find the value for x

Answer 1

Answer:

x = 7

Step-by-step explanation:

A, B, and C are collinear B is between A and C.

AC = AB + BC

2x + 1 = x + 4 + 2x - 10

2x + 1 = 3x - 6

2x - 3x = - 6 - 1

- x = - 7

x = 7
