$$\left. \begin{array} { l } { x = 5 }\\ { y = 2 x + 1 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

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

$$d=11$$

Solution Steps

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

$$y=2\times 5+1$$

Multiply 2 and 5 to get 10.

$$y=10+1$$

Add 10 and 1 to get 11.

$$y=11$$

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

$$z=11$$

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

$$a=11$$

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

$$b=11$$

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

$$c=11$$

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

$$d=11$$

The system is now solved.

$$x=5 y=11 z=11 a=11 b=11 c=11 d=11$$
