Solve {l}{11-7n=2}{o=n}{text{Solvefor}ptext{where}}{p=o}

$$\left. \begin{array} { l } { 11 - 7 n = 2 }\\ { o = n }\\ { \text{Solve for } p \text{ where} } \\ { p = o } \end{array} \right.$$

Solve for n, o, p

$$p = \frac{9}{7} = 1\frac{2}{7} \approx 1.285714286$$

Solution Steps

Consider the first equation. Subtract 11 from both sides.

$$-7n=2-11$$

Subtract 11 from 2 to get -9.

$$-7n=-9$$

Divide both sides by -7.

$$n=\frac{-9}{-7}$$

Fraction \frac{-9}{-7} can be simplified to \frac{9}{7} by removing the negative sign from both the numerator and the denominator.

$$n=\frac{9}{7}$$

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

$$o=\frac{9}{7}$$

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

$$p=\frac{9}{7}$$

The system is now solved.

$$n=\frac{9}{7} o=\frac{9}{7} p=\frac{9}{7}$$
