Solve the system of equations by transforming a matrix representing the system of equation into reduced row echelon form. 2x+y−3z=−19
x+2y+z=−4
x−y+5z=21

What is the system of equations in reduced row echelon and solution to system of equations?

Problem one: x = -19/2 - y/2 + 3z/2

Problem two: x = -4 - 2y - z

Problem thee: x = 21 + y - 5z

Step-by-step explanation:

So what I did with all problems was Move all terms not containing x to the right side of the equation. To solve the systems of equations of each problem.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
