Solve {l}{x=4}{y=12^x}{z={(y/6)}}{text{Solvefor}atext{where}}{a=z}

$$\left. \begin{array} { l } { x = 4 }\\ { y = 12 ^ {x} }\\ { z = {(\frac{y}{6})} }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Solve for x, y, z, a

$$a=3456$$

Solution Steps

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

$$y=12^{4}$$

Calculate 12 to the power of 4 and get 20736.

$$y=20736$$

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

$$z=\frac{20736}{6}$$

Divide 20736 by 6 to get 3456.

$$z=3456$$

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

$$a=3456$$

The system is now solved.

$$x=4 y=20736 z=3456 a=3456$$
