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)

\rm \mathrm{Substitute\:}x=\dfrac{5-3y+z}{2}   (from the equation 1 and 2)

After solving:

\rm \begin{bmatrix}-7y+z+10=-1\\ \dfrac{5y+3z+5}{2}=12\end{bmatrix}

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.

zaharov [31]

answer:

-13/12

Step-by-step explanation:

use the formula to find slope using points

it is: y2-y1/x2-x1

plug in point values into formula

-3 = x1. 9 = x2

-2= y1. -15 = y2

-15-(-2)/ 9-(-3)

-13/12
