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

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

$$d=2$$

Solution Steps

Consider the first equation. Multiply both sides by 1.

$$x=2\times 1$$

Multiply 2 and 1 to get 2.

$$x=2$$

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

$$y=2$$

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

$$z=2$$

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

$$a=2$$

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

$$b=2$$

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

$$c=2$$

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

$$d=2$$

The system is now solved.

$$x=2 y=2 z=2 a=2 b=2 c=2 d=2$$
