$$\left. \begin{array} { l } { -15 = -4 m }\\ { n = 5 }\\ { o = n }\\ { p = o }\\ { q = p }\\ { r = q }\\ { s = r }\\ { t = s }\\ { u = t }\\ { v = u }\\ { w = v }\\ { x = w }\\ { y = x }\\ { \text{Solve for } z \text{ where} } \\ { z = y } \end{array} \right.$$

Solve for m, n, o, p, q, r, s, t, u, v, w, x, y, z

$$z=5$$

Solution Steps

Consider the first equation. Divide both sides by -4.

$$\frac{-15}{-4}=m$$

Fraction \frac{-15}{-4} can be simplified to \frac{15}{4} by removing the negative sign from both the numerator and the denominator.

$$\frac{15}{4}=m$$

Swap sides so that all variable terms are on the left hand side.

$$m=\frac{15}{4}$$

The system is now solved.

$$m=\frac{15}{4} n=5 o=5 p=5 q=5 r=5 s=5 t=5 u=5 v=5 w=5 x=5 y=5 z=5$$
