The solve command

Example 4

The solvecommand can also be used to solve a system of linear equations. For example, let us find the solutions of the system ${\begin{matrix} x + y = 2 \\ x - y = 0 \end{matrix}$ .

Here is an example of the solution of a 3 by 3 system with variables x, y, and z.

Solve the system:

{\begin{matrix} x + y + z = 1 \\ 3 x + y = 3 \\ x - 2 y - z = 0 \end{matrix}

Try this!

Solve the system: ${\begin{matrix} 4 x + 3 y = 12 \\ 5 x - 7 y = 35 \end{matrix}$ .
