Verify that the values of the variables listed are solutions of the system of equations.

$\{\begin{array}{r} \begin{array}{rcl} 4 x - z & = & 7 \\ 8 x + 5 y - z & = & 0 \end{array} \\ - x - y + 5 z = 6 \end{array} x = 2, y = - 3, z = 1; (2, - 3, 1)$

Graph each inequality by hand.

$2 x + y \geq 6$

Verify that the values of the variables listed are solutions of the system of equations.

$\{\begin{matrix} \begin{array}{rcl} 3 x + 3 y + 2 z & = & 4 \\ x - 3 y + z & = & 10 \end{array} \\ 5 x - 2 y - 3 z = 8 \end{matrix} x = 2, y = - 2, z = 2; (2, - 2, 2)$

Solve each system of equations. If the system has no solution, say that it is inconsistent.

$\{\begin{matrix} x - y = 5 \\ - 3 x + 3 y = 2 \end{matrix}$

Solve the equation:

$3 x + 4 = 8 - x$
