Solve {l}{-5x=35}{y=x}{z=y}{a=z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { -5 x = 35 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Solve for x, y, z, a, b, c

$$c=-7$$

Solution Steps

Consider the first equation. Divide both sides by -5.

$$x=\frac{35}{-5}$$

Divide 35 by -5 to get -7.

$$x=-7$$

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

$$y=-7$$

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

$$z=-7$$

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

$$a=-7$$

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

$$b=-7$$

Consider the equation (6). Insert the known values of variables into the equation.

$$c=-7$$

The system is now solved.

$$x=-7 y=-7 z=-7 a=-7 b=-7 c=-7$$
