36 : x + 12 : x = 18
( 36 + 12 ) : x = 18
48 : x = 18
x = 48 : 18
x = 2,6666
Vậy x = 2 , 6666
36 : x + 12 : x = 18
36 * 1/x + 12 * 1/x = 18
(36+12) * 1/x = 18
48 * 1/x = 18
48 : x = 18
x = 48 : 18
x = ...
36 : x + 12 : x = 18
( 36 +12 ) : x = 18
48 : x = 18
x = 48 : 18
x = 2,6666
36:x+12:x=18
(36+12):x=18
48 :x=18
x=48:18
x=8/3
36 : X + 12 : X = 18
( 36 + 12 ) : X = 18
48 : X = 18
X = 48 : 18
X = \(\frac{48}{18}=\frac{8}{3}\)

36 : x + 12 : x = 18
36 × 1/x + 12 × 1/x = 18
( 36 + 12 ) × 1/x = 18
48 × 1/x = 18
48 : x = 18
x = 48 : 18
x = 2, 6666
\(36:x+12:x=18\)
\(\Rightarrow\left(36+12\right):x=18\)
\(\Rightarrow48:x=18\)
\(\Rightarrow x=48:18\)
\(\Rightarrow x=\frac{8}{3}\)
Vậy \(x=\frac{8}{3}\)
