Solve {l}{2x=22}{y=x+1}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 2 x = 22 }\\ { y = x + 1 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for x, y, z, a, b

$$b=12$$

Solution Steps

Consider the first equation. Divide both sides by 2.

$$x=\frac{22}{2}$$

Divide 22 by 2 to get 11.

$$x=11$$

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

$$y=11+1$$

Add 11 and 1 to get 12.

$$y=12$$

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

$$z=12$$

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

$$a=12$$

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

$$b=12$$

The system is now solved.

$$x=11 y=12 z=12 a=12 b=12$$
