Question

x(7500/x)=(x-5)[7500/x]+75

Answer 1

Respuesta:

$x\left(\frac{7500}{x}\right)=\left(x-5\right)\left[\frac{7500}{x}\right]+75\quad :\quad x=500$

Proceso:

$x\left(\frac{7500}{x}\right)=\left(x-5\right)\left[\frac{7500}{x}\right]+75$

Simplificación:

$7500=\frac{7500\left(x-5\right)}{x}+75$

$7500x=7500\left(x-5\right)+75x$

$7500x=7575x-37500$

$-75x=-37500$
