Question

\(\dfrac{x+3}{x-2}=\dfrac{-2}{3}\)

Answer 1

ĐKXĐ: x<>2

\(\dfrac{x+3}{x-2}=\dfrac{-2}{3}\)

=>3(x+3)=-2(x-2)

=>3x+9=-2x+4

=>5x=-5

=>x=-1(nhận)

Answer 2

ĐKXĐ: x $\ne$ 2
$\Leftrightarrow$ $3(x + 3) = -2(x - 2)$
$\Leftrightarrow$ $3x + 9 = -2x + 4$
$\Leftrightarrow$ $5x = -5$
$\Leftrightarrow$ $x = -1$ (nhận)
