Tìm x biết :
x + 4/5 = 4/5 + ( 3/7 + 3/5 ) 5/7 + x/35 = 4/5
x < 3/4 + 2 2/3 + 1 < x < 5/6 + 4
x< 5/6 - 3/4 2/3 < x < 2 - 5/6
tìm x: x+4/5=3/2,x-3/2=11/4,25/3-x=5/6
tìm X
X - 6/5 = 3/4 : 3/16 X x 4/5 = 3/4 + 2/5
Bài 3. Tìm x: a) x x 1/5 + 2/6 = 5/9
b) 2/5 : x - 1/3 = 1/5
Tìm x :
X + 5/9 = 4/3 X - 4/9 = 1/2 6/13 + X = 7/6 13/5 - X = 5/6
Giúp mình ạ !
Tìm x:
X : 3/4=5/6
X-2/3=4/6
7/10 : X=7/2
5/8 : X=5
Bài 2: tìm x: câu 1: 1/5 × x =4/6. Câu 2 : x/6 × 5/8= 5/12. Câu 3 : 5/9 ÷ 3/x =5/27. Mong các bạn giúp.
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 X x 3/5=2/3+1/6
