5 . 6 = x . 6 + 6
30 = x. 6 + 6
= > x . 6 = 30 - 6
x . 6 = 24
Vậy x = 24 : 6
x = 4
tích nha!
\(\Rightarrow\left[{}\begin{matrix}\dfrac{2}{3}-x=3\sqrt{3}\\\dfrac{2}{3}-x=-3\sqrt{3}\end{matrix}\right.\)\(\Rightarrow\left[{}\begin{matrix}x=\dfrac{2-9\sqrt{3}}{3}\\x=\dfrac{2+9\sqrt{3}}{3}\end{matrix}\right.\)

725 : x + 175 : x = 5
(725+175):x=5
900:x=5
x=900:5
x=180
( 725 + 175 ) : x = 5
900 : x = 5
x = 900 : 5
x = 180
