Answer:
The solutions for the given system of equations are:
Step-by-step explanation:
Given the equation system:
We obtain the following matrix:
<u>Step 1:</u> Multiply the fisrt row by 1/3.
<u>Step 2:</u> Sum the first row and the second row.
<u>Step 3:</u> Multiply the second row by 3/4.
<u>Step 4:</u> Multiply the second row by -1/3 and sum the the first row.
The result of the reduced matrix is:
This is equal to:
These are the solutions for the system of equations in terms of z, where z can be any number.
