Solve {l}{x/18=2/43}{y=x}{text{Solvefor}ztext{where}}{z=y}

$$\left. \begin{array} { l } { \frac{x}{18} = \frac{2}{43} }\\ { y = x }\\ { \text{Solve for } z \text{ where} } \\ { z = y } \end{array} \right.$$

Solve for x, y, z

$$z=\frac{36}{43}\approx 0.837209302$$

Solution Steps

Consider the first equation. Multiply both sides by 18.

$$x=\frac{2}{43}\times 18$$

Multiply \frac{2}{43} and 18 to get \frac{36}{43}.

$$x=\frac{36}{43}$$

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

$$y=\frac{36}{43}$$

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

$$z=\frac{36}{43}$$

The system is now solved.

$$x=\frac{36}{43} y=\frac{36}{43} z=\frac{36}{43}$$
