Question

Given a line segment that contains the points A,B, & C in order, if AB = x - 2, and BC = 2x + 6, and AC = 19, find x.

Answer 1

Answer:

The answer to your question is: x = 5 units

Step-by-step explanation:

Data

AB = x - 2

BC = 2x + 6

AC = 19

x = ?

Process

                           AB + BC = AC

Solve for x,                        x - 2 + 2x + 6 = 19

                                           3x + 4 = 19

                                           3x = 19 - 4

                                           3x = 15

                                           x = 15 / 3

                                           x = 5 units
