$$\left. \begin{array} { l } { -2 m = -18 }\\ { n = m }\\ { o = n }\\ { p = o }\\ { q = p }\\ { r = q }\\ { s = r }\\ { t = s }\\ { \text{Solve for } u \text{ where} } \\ { u = t } \end{array} \right.$$

Solve for m, n, o, p, q, r, s, t, u

$$u=9$$

Solution Steps

Consider the first equation. Divide both sides by -2.

$$m=\frac{-18}{-2}$$

Divide -18 by -2 to get 9.

$$m=9$$

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

$$n=9$$

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

$$o=9$$

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

$$p=9$$

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

$$q=9$$

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

$$r=9$$

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

$$s=9$$

Consider the equation (8). Insert the known values of variables into the equation.

$$t=9$$

Consider the equation (9). Insert the known values of variables into the equation.

$$u=9$$

The system is now solved.

$$m=9 n=9 o=9 p=9 q=9 r=9 s=9 t=9 u=9$$
