Hope this helped! :)
The values of x, y, and z are 1, 2, and 3 respectively after using the substitution method.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have a linear equation in three variable:
2x + 3y - z = 5 ...(1)
4x - y - z = -1 ...(2)
x + 4y + z = 12 ...(3)
(from the equation 1 and 2)
After solving:
From the above, two equations:
y =2
z =3
Plug the above values in equation 1
x = 1
Thus, the values of x, y, and z are 1, 2, and 3 respectively after using the substitution method.

Answer:
The chord is bisected ⇒ 3rd answer
Step-by-step explanation:
* Lets revise some facts in the circle to solve the problem
- A chord in a circle is the segments whose endpoints lie on the
circumference of the circle
- A diameter of a circle is a chord passes through the center of the
circle
- The diameter is the longest chord in the circle
- Any line passes through the center of the circle and perpendicular
to a chord on the circle bisects it
* Lets solve the problem
∵ The diameter of the circle passes through the center of the circle
∵ The diameter intersects a chord of a circle at a perpendicular
∴ The diameter is perpendicular to the chord
∵ Any line passes through the center of the circle and perpendicular
to a chord on the circle bisects it
∴ The diameter bisects the chord
* The chord is bisected
