Solve {l}{0*0+x=1}{y=x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 0 \cdot 0 + x = 1 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for x, y, z, a, b

$$b=1$$

Solution Steps

Consider the first equation. Multiply 0 and 0 to get 0.

$$0+x=1$$

Anything plus zero gives itself.

$$x=1$$

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

$$y=1$$

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.

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