\(x=1-\dfrac{2}{9}\\ x=\dfrac{9}{9}-\dfrac{2}{9}\\ x=\dfrac{7}{9}\)
\(x=1-\dfrac{2}{9}\\ =>x=\dfrac{9}{9}-\dfrac{2}{9}=\dfrac{7}{9}\)
Tìm X, biết:
A) X x 2/5 + 1/2 x X = 9
B) 1/9 : X + 3/9 : X =5/7
tìm x 2*x+1/9=5/3 b 2/9*x+1/5*x=2/3-3/5
1. Tìm X, biết: x - \(\dfrac{2}{3}\) x ( X + 9 ) = 1
2. Tìm X, biết: X - \(\dfrac{11}{15}\) = \(\dfrac{3+X}{5}\)
Tìm x :
a, x - 3/2 = 4/3 b, 2/5 * x = 1/3
c, x - 4/9 = 3/7 : 9/14 d, 3/5 * x - 1/2 = 1/5
Tìm x:
x : 3/4= 9/14 - 1/7
X x 1/2 - X x 1/4 = 2/3
help mình
tìm x
x+1/9=2 x:1/3=5-1/5
Bài 3. Tìm x: a) x x 1/5 + 2/6 = 5/9
b) 2/5 : x - 1/3 = 1/5
Tìm X
a) 4/7 x X - 1/5 = 5/9 b)9/15 + 11/15 : X = 2/3
câu 9: tìm x a) 9/7 : x = 3/4 b) x - 1/6 = 13/4 - 5/2
