Answer 1

Given the following System of equations:

`\begin{cases}-5x+3y+6z=4 \\ -3x+y+5z=-5 \\ -4x+2y+z=13\end{cases}`

You can solve it using the Elimination method as following:

1. Multiply the second equation by -3.

2. Add the first equation and the new second equation.

Then:

`\begin{cases}-5x+3y+6z=4 \\ 9x-3y-15z=15 \\ -------------- \\ 4x-9z=19\end{cases}`

3. Multiply the original second equation by -2.

4. Add this new equation and the third original equation.

Then:
