Steps to solve system of linear equations with three variables:

$\textbf{Step }1$ $\rightarrow$ Eliminate any one variable from equation $\left(1\right)$ and equation $\left(2\right)$.

$\textbf{Step}$ $2$ $\rightarrow$ Eliminate the same variable from equation $\left(1\right)$ and equation $\left(3\right)$ or from equation $\left(2\right)$ and equation $\left(3\right)$.

$\textbf{Step}$ $3$ $\rightarrow$ Consider the equations obtain from step $1$ and step $2$ as system of linear equations with two variables. Eliminate one variable and solve for another.

$\textbf{Step}$ $4$ $\rightarrow$ Substitute the value of variables in equations and solve for third variables.
