$$\left. \begin{array} { l } { x = 3 }\\ { y = 2 x - 6 }\\ { z = x }\\ { a = y }\\ { b = z }\\ { \text{Solve for } c,d \text{ where} } \\ { c = a }\\ { d = b } \end{array} \right.$$

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

$$c=0$$

$$d=3$$

Solution Steps

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

$$y=2\times 3-6$$

Multiply 2 and 3 to get 6.

$$y=6-6$$

Subtract 6 from 6 to get 0.

$$y=0$$

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

$$a=0$$

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

$$c=0$$

The system is now solved.

$$x=3 y=0 z=3 a=0 b=3 c=0 d=3$$
