Solve {l}{X/{(-8)}=1/2}{a=X}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { X / {(-8)} = \frac{1}{2} }\\ { a = X }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Solve for X, a, b, c, d

$$d=-4$$

Solution Steps

Consider the first equation. Multiply both sides by -8.

$$X=\frac{1}{2}\left(-8\right)$$

Multiply \frac{1}{2} and -8 to get -4.

$$X=-4$$

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

$$a=-4$$

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

$$b=-4$$

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

$$c=-4$$

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

$$d=-4$$

The system is now solved.

$$X=-4 a=-4 b=-4 c=-4 d=-4$$
