Question

Resolver: $\frac{x}{b} - n = b - \frac{x}{n}$

Answer 1

Resposta:

S = {bn}

Explicação passo-a-passo:

$\frac{x}{b} - n = b - \frac{x}{n} \\ \frac{x}{b} + \frac{x}{n} = b + n \\ \frac{nx + bx}{bn} = b + n \\ nx + bx = bn(b + n) \\ x(b + n) = bn(b + n) \\ x = \frac{bn(b + n)}{(b + n)} \\ x = bn$
