$$\left. \begin{array} { l } { 1862 + x = 4 }\\ { y = -8 + 7 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

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

$$d=-1$$

Solution Steps

Consider the first equation. Subtract 1862 from both sides.

$$x=4-1862$$

Subtract 1862 from 4 to get -1858.

$$x=-1858$$

Consider the second equation. Add -8 and 7 to get -1.

$$y=-1$$

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.

$$b=-1$$

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

$$c=-1$$

Consider the equation (7). Insert the known values of variables into the equation.

$$d=-1$$

The system is now solved.

$$x=-1858 y=-1 z=-1 a=-1 b=-1 c=-1 d=-1$$
