Solve {l}{6m+9=21}{n=m}{o=n}{p=o}{text{Solvefor}qtext{where}}{q=p}

$$\left. \begin{array} { l } { 6 m + 9 = 21 }\\ { n = m }\\ { o = n }\\ { p = o }\\ { \text{Solve for } q \text{ where} } \\ { q = p } \end{array} \right.$$

Solve for m, n, o, p, q

$$q=2$$

Solution Steps

Consider the first equation. Subtract 9 from both sides.

$$6m=21-9$$

Subtract 9 from 21 to get 12.

$$6m=12$$

Divide both sides by 6.

$$m=\frac{12}{6}$$

Divide 12 by 6 to get 2.

$$m=2$$

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

$$n=2$$

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

$$o=2$$

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

$$p=2$$

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

$$q=2$$

The system is now solved.

$$m=2 n=2 o=2 p=2 q=2$$
