\(\dfrac{x-2}{x}\)+3=\(\dfrac{5}{7}\)
\(\dfrac{x-2}{x}\) =\(\dfrac{5}{7}\)-3
\(\dfrac{x-2}{x}\) =\(\dfrac{5}{7}\)-\(\dfrac{21}{7}\)
\(\dfrac{x-2}{x}\) = \(\dfrac{-16}{7}\)
(x-2)∙7 =x∙-16
7x-14=-16x
-16x-7x=-14
-23x =-14
x =-14:-23
x = \(\dfrac{14}{23}\)
Chưa có đáy bé
Diện tích hình thang ABCD là:
25∙((đáy bé+50):2)=(cm2)
-12x-7x=-76
-19x =-76
x =-76:-19
x = 4

Các số vừa chia hết cho 2 vừa chia hết cho 5 là: 2 000, 190
