$$\left. \begin{array} { l } { m = 30 }\\ { n = \frac{1}{4} }\\ { o = 1 m + 8 - 12 n }\\ { p = o }\\ { q = p }\\ { \text{Solve for } r \text{ where} } \\ { r = q } \end{array} \right.$$

Solve for m, n, o, p, q, r

$$r=35$$

Solution Steps

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

$$o=1\times 30+8-12\times \frac{1}{4}$$

Multiply 1 and 30 to get 30.

$$o=30+8-12\times \frac{1}{4}$$

Add 30 and 8 to get 38.

$$o=38-12\times \frac{1}{4}$$

Multiply -12 and \frac{1}{4} to get -3.

$$o=38-3$$

Subtract 3 from 38 to get 35.

$$o=35$$

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

$$p=35$$

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

$$q=35$$

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

$$r=35$$

The system is now solved.

$$m=30 n=\frac{1}{4} o=35 p=35 q=35 r=35$$
