\(x+\dfrac{2}{5}=\dfrac{1}{2}\)
\(x=\dfrac{1}{2}-\dfrac{2}{5}\)
\(x=\dfrac{1}{10}\)
\(x+\dfrac{2}{5}=\dfrac{1}{2}\)
\(x=\dfrac{1}{2}-\dfrac{2}{5}\)
\(x=\dfrac{1}{10}\)
Bài 1: Tính
a) 1/3 + 1/5 - 1/4 b) 7/8 - ( 1/4 + 2/5 ) c) 5/11 - ( 3/5 - 6/11 )
Bài 2: Tìm x
a) x + 2/5 = 1/2 b) x + 3/7 = 2/5 + 3/10 c) 19/20 - x = 8/5 - 3/4
Bài 3: Tìm số tự nhiên x, biết:
a ) 4/7 < x < 1/2 + 10/3 b) 3/10 + 8/5 < x < 2/5 + 5
Giúp mình nha ^^ Ai nhanh mình Tick !!!!!!!!!❤❤
tìm x 2*x+1/9=5/3 b 2/9*x+1/5*x=2/3-3/5
bài 1 : tìm x
a, 1/5=5=1/2 b, 11/5+x=9
c,5-x=7/17 d, x-1/3=16/5:3/2
e,8/9:x=11/2 g, x:31/5=2+7/2
h,7/8x íc=29/2-2
giải hết ra cho mink nha
Bài 3. Tìm x: a) x x 1/5 + 2/6 = 5/9
b) 2/5 : x - 1/3 = 1/5
Tìm X, biết:
A) X x 2/5 + 1/2 x X = 9
B) 1/9 : X + 3/9 : X =5/7
Tìm x :
3/7 x x = 1/3
x : 6/8 = 2/5
x - 2/3 = 5/6
x - 2/5 - 4/35 = 1/7
Tìm x:
5/2 - x = 5/6 x 1/2
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
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
x+1/9=2 x:1/3=5-1/5
