Solve {l}{x/3*7=-5}{y=0*4}{text{Solvefor}ztext{where}}{z=y}

$$\left. \begin{array} { l } { x / 3 \cdot 7 = -5 }\\ { y = 0 \cdot 4 }\\ { \text{Solve for } z \text{ where} } \\ { z = y } \end{array} \right.$$

Solve for x, y, z

$$z=0$$

Solution Steps

Consider the first equation. Divide both sides by 7.

$$\frac{x}{3}=-\frac{5}{7}$$

Multiply both sides by 3.

$$x=-\frac{5}{7}\times 3$$

Multiply -\frac{5}{7} and 3 to get -\frac{15}{7}.

$$x=-\frac{15}{7}$$

Consider the second equation. Multiply 0 and 4 to get 0.

$$y=0$$

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

$$z=0$$

The system is now solved.

$$x=-\frac{15}{7} y=0 z=0$$
