$$\left. \begin{array} { l } { u = 5 }\\ { a = 3 }\\ { t = 4 }\\ { v = {(2)} a }\\ { w = v }\\ { x = w }\\ { y = x }\\ { \text{Solve for } z \text{ where} } \\ { z = y } \end{array} \right.$$

Solve for u, a, t, v, w, x, y, z

$$z=6$$

Solution Steps

Consider the fourth equation. Insert the known values of variables into the equation.

$$v=2\times 3$$

Multiply 2 and 3 to get 6.

$$v=6$$

Consider the fifth equation. Insert the known values of variables into the equation.

$$w=6$$

Consider the equation (6). Insert the known values of variables into the equation.

$$x=6$$

Consider the equation (7). Insert the known values of variables into the equation.

$$y=6$$

Consider the equation (8). Insert the known values of variables into the equation.

$$z=6$$

The system is now solved.

$$u=5 a=3 t=4 v=6 w=6 x=6 y=6 z=6$$
