Use the left-to right elimination method to solve the system in Problems 27-32.

{ x + 3 y 8 z = 20 y 3 z = 11 2 y + 7 y = 4

To determine

To calculate: The solution of the system of equations {x+3y8z=20y3z=112y+7z=4 by using the left-to-right elimination method.

Explanation of Solution

Given Information:

The given equations are:

x+3y8z=20 …… (1)

y3z=11 …… (2)

2y+7z=4 …… (3)

Formula Used:

Elimination method:

To solve the system of equations, first transform the system and cancel out one variable. After that, solve the obtained equation for the variable involved. Now, substitute the value of the obtained variable into any of the original equations to get the value of another variable.

Calculation:

Solve equation (2) and equation (3) to find the value of yandz.

Multiply equation (2) with 2.

2y+6z=22 …… (4)

Add equation (3) and equation (4).

2y+7z2y+6z=42213z=26z=2

Substitute 2 for z in equation (2).

y3(2)=11y+6=11y=116y=5

Substitute 2 for z and 5 for y in equation (1)
