Solve the system using either Gaussian elimination with back-substitution or Gauss-Jordan elimination. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, set y = t and solve for x in terms of t.) −3x + 5y = −34 3x + 4y = −11 4x − 8y = 52

The solution of the system of equations is .

Step-by-step explanation:

Gauss–Jordan elimination is a procedure for converting a matrix to reduced row echelon form using elementary row operations.

It relies upon three elementary row operations one can use on a matrix:

To find the solution of the system

using Gauss-Jordan elimination you must:

Step 1: Transform the augmented matrix to the reduced row echelon form.

In an augmented matrix, each row represents one equation in the system and each column represents a variable or the constant terms.

This is the augmented matrix that represents the system.

Using elementary matrix operations, we get that

Row Operation 1: Add row 1 to row 2

Row Operation 2: Divide row 1 by −3

Row Operation 3: Subtract row 1 multiplied by 4 from row 3

Row Operation 4: Divide row 2 by 9

Row Operation 5: Add row 2 multiplied by 5/3 to row 1

Row Operation 6: Add row 2 multiplied by 4/3 to row 3

This is the reduced row echelon form matrix

Step 2: Interpret the reduced row echelon form

The reduced row echelon form of the augmented matrix corresponds to the system

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
