Solve {l}{x=9}{y=3*{(x-6)}-8}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x = 9 }\\ { y = 3 \cdot {(x - 6)} - 8 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for x, y, z, a, b

$$b=1$$

Solution Steps

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

$$y=3\left(9-6\right)-8$$

Subtract 6 from 9 to get 3.

$$y=3\times 3-8$$

Multiply 3 and 3 to get 9.

$$y=9-8$$

Subtract 8 from 9 to 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.

$$b=1$$

The system is now solved.

$$x=9 y=1 z=1 a=1 b=1$$
