$\dfrac{-(x – 3)}{2} – 2 = \dfrac{(5(x+2)}{4}$ $⇒ \dfrac{-(x – 3)}{2} – 2 = \dfrac{5x + 10}{4}$ $⇒ \dfrac{-(x – 3)}{2} – \dfrac{4}{2} = \dfrac{5x + 10}{4}$ $⇒ \dfrac{-(x – 3)2 – 8}{4} = \dfrac{5x + 10}{4}$ $⇒ -2(x-3)-8 = 5x+10$ $⇒ -2x – (-6) – 8 = 5x + 10$ $⇒ -2x + 6 + (-8) = 5x+10$ $⇒ -2x -2 = 5x + 10$ $⇒ -2x – 5x = 10 + 2$ $⇒ -7x = 12$ $⇒ x = \dfrac{-12}{7}$ Bình luận

`-(x-3)/2-2=(5(x+2))/4`
`-> -(x-3)/2-2=(5x+10)/4`
`-> -2(x-3)-8=5x+10`
`-> -2x+6-8=5x+10`

$\dfrac{-(x – 3)}{2} – 2 = \dfrac{(5(x+2)}{4}$
$⇒ \dfrac{-(x – 3)}{2} – 2 = \dfrac{5x + 10}{4}$
$⇒ \dfrac{-(x – 3)}{2} – \dfrac{4}{2} = \dfrac{5x + 10}{4}$
$⇒ \dfrac{-(x – 3)2 – 8}{4} = \dfrac{5x + 10}{4}$
$⇒ -2(x-3)-8 = 5x+10$
$⇒ -2x – (-6) – 8 = 5x + 10$
$⇒ -2x + 6 + (-8) = 5x+10$
$⇒ -2x -2 = 5x + 10$
$⇒ -2x – 5x = 10 + 2$
$⇒ -7x = 12$
$⇒ x = \dfrac{-12}{7}$
