Question

$$9n=n+4; 9_{n}=(-2)^{n}$$

Solve for n, o

$o=9$

Solution Steps

Consider the first equation. Subtract $n$ from both sides.

$$9n-n=4$$

Combine $9n$ and $-n$ to get $8n$.

$$8n=4$$

Divide both sides by $8$.

$$n=\frac{4}{8}$$

Reduce the fraction $\frac{4}{8}$ to lowest terms by extracting and canceling out $4$.

$$n=\frac{1}{2}$$

The system is now solved.

$$n=\frac{1}{2}$$ $$o=9$$
