Solve {l}{x=2}{y=10x+4}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x = 2 }\\ { y = 10 x + 4 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for x, y, z, a, b

$$b=24$$

Solution Steps

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

$$y=10\times 2+4$$

Multiply 10 and 2 to get 20.

$$y=20+4$$

Add 20 and 4 to get 24.

$$y=24$$

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

$$z=24$$

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

$$a=24$$

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

$$b=24$$

The system is now solved.

$$x=2 y=24 z=24 a=24 b=24$$
