Resolver nx-x=(n+3)(n+2)

$$n x - x = ( n + 3 ) ( n + 2 )$$

Resolver x

$$x=\frac{\left(n+2\right)\left(n+3\right)}{n-1}$$

$$n\neq 1$$

Pasos para resolver unha ecuación lineal

Usa a propiedade distributiva para multiplicar n+3 por n+2 e combina os termos semellantes.

$$nx-x=n^{2}+5n+6$$

Combina todos os termos que conteñan x.

$$\left(n-1\right)x=n^{2}+5n+6$$

Divide ambos lados entre n-1.

$$\frac{\left(n-1\right)x}{n-1}=\frac{\left(n+2\right)\left(n+3\right)}{n-1}$$

A división entre n-1 desfai a multiplicación por n-1.

$$x=\frac{\left(n+2\right)\left(n+3\right)}{n-1}$$

Resolver n (complex solution)

$$n=\frac{-\sqrt{x^{2}-14x+1}+x-5}{2}$$

$$n=\frac{\sqrt{x^{2}-14x+1}+x-5}{2}$$

Resolver n

$$n=\frac{-\sqrt{x^{2}-14x+1}+x-5}{2}$$

$$n=\frac{\sqrt{x^{2}-14x+1}+x-5}{2}\text{, }x\geq 4\sqrt{3}+7\text{ or }x\leq 7-4\sqrt{3}$$
