<h2>
Explanation:</h2>
We have the following system of three linear equations:

Let's use elimination method in order to get the solution of this system of equation, so let's solve this step by step.
Step 1: Multiply first equation by
and add the result to the second equation. So we get:

Step 2: Multiply first equation by −2 and add the result to the third equation. So we get:

Step 3: Multiply second equation by −32 and add the result to the third equation. So we get:

Step 4: solve for z.

Step 5: solve for y.

Step 6: solve for x by substituting
and
into the first equation:

Finally:
