Question

1/3 (3×+2)-2/5(5×-7)=-3/4+2×
ayudenme a resolver esto porfa​

Answer 1

Respuesta:

Explicación paso a paso:

$\frac{1}{3}\left(3x+2\right)-\frac{2}{5}\left(5x-7\right)=\frac{-3}{4+2x}$

$\frac{1}{3}\left(3x+2\right)-\frac{2}{5}\left(5x-7\right)=-\frac{3}{4+2x}$

$\frac{1}{3}\left(3x+2\right)\cdot \:30\left(x+2\right)-\frac{2}{5}\left(5x-7\right)\cdot \:30\left(x+2\right)=-\frac{3}{4+2x}\cdot \:30\left(x+2\right)$

simplificar

$10\left(3x+2\right)\left(x+2\right)-12\left(5x-7\right)\left(x+2\right)=-45$

$x=-\frac{-22+\sqrt{8074}}{30},\:x=\frac{22+\sqrt{8074}}{30}$
