$$\left. \begin{array} { l } { x - 2 = 6 }\\ { y = 2 \cdot 2 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

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

$$d=4$$

Solution Steps

Consider the first equation. Add 2 to both sides.

$$x=6+2$$

Add 6 and 2 to get 8.

$$x=8$$

Consider the second equation. Multiply 2 and 2 to get 4.

$$y=4$$

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

$$z=4$$

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

$$a=4$$

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

$$b=4$$

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

$$c=4$$

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

$$d=4$$

The system is now solved.

$$x=8 y=4 z=4 a=4 b=4 c=4 d=4$$
