$$\left. \begin{array} { l } { x = -1 }\\ { y = -x ^ {2} }\\ { z = y }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

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

$$c=-1$$

Solution Steps

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

$$y=-\left(-1\right)^{2}$$

Calculate -1 to the power of 2 and get 1.

$$y=-1$$

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

$$z=-1$$

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

$$a=-1$$

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

$$b=-1$$

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

$$c=-1$$

The system is now solved.

$$x=-1 y=-1 z=-1 a=-1 b=-1 c=-1$$
