Question

x-7/x+3=10/x+3-3 solución​

Answer 1

Respuesta:

$\frac{x-7}{x+3}=\frac{10}{x+3-3}\quad :\quad x=\frac{17+\sqrt{409}}{2},\:x=\frac{17-\sqrt{409}}{2}\quad \left(\mathrm{Decimal}:\quad x=18.61187\dots ,\:x=-1.61187\dots \right$

Explicación paso a paso:

$\frac{x-7}{x+3}=\frac{10}{x+3-3}$

$\left(x-7\right)x=\left(x+3\right)\cdot \:10$

$x=\frac{17+\sqrt{409}}{2},\:x=\frac{17-\sqrt{409}}{2}x=\frac{17+\sqrt{409}}{2},\:x=\frac{17-\sqrt{409}}{2}$

$x=\frac{17+\sqrt{409}}{2},\:x=\frac{17-\sqrt{409}}{2}$

Answer 2

RESPUESTA:

x-7/x+3=10/x+3-3

$\frac{x-7}{x+3} =\frac{10}{x+3-3}\\\\\frac{x-7}{x+3} = \frac{10}{x}\\\\x(x-7) = (x+3)(10)\\\\x^{2} -7x = 10x +30\\\\x^{2} -7x -10x - 30 = 0\\\\x^{2} -17 -30 = 0$
