solving a linear equation we conclude that the value of x must be 6.

<h3>How to find the value of x?</h3>

On the statement we have the relations:

AB = BC

BC = CD

For the transitive property, then we have that:

AB = CD

Replacing the equations in the image, we get:

2x + 1 = 4x - 11

Solving this linear equation for x we get:

1 + 11 = 4x - 2x

12 = 2x

12/2 = x

6 = x

So yes, solving that linear equation we conclude that the value of x must be 6.
