Solve {l}{x=-2}{y=8x}{z=y}{a=z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { x = -2 }\\ { y = 8 x }\\ { z = y }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Solve for x, y, z, a, b, c

$$c=-16$$

Solution Steps

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

$$y=8\left(-2\right)$$

Multiply 8 and -2 to get -16.

$$y=-16$$

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

$$z=-16$$

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

$$a=-16$$

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

$$b=-16$$

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

$$c=-16$$

The system is now solved.

$$x=-2 y=-16 z=-16 a=-16 b=-16 c=-16$$
