Tìm x
x - 4/5 = 3/7
x + 3/7 = 4/5
19/20 - x = 8/5 - 3/4
4/5 x X = 6/9 - 4/7
x : 7/9 = 6/8
2/3 - x/6 = 6/18

nhanh lên giúp mình với, ai thích và trả lời milk sẽ tick đúng
Tính nhanh các biểu thức sau :
a) (45 – 5 x 9) x 1 x 2 x 3 x 4 x 5 x 6 x 7
b) (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10) x (72 – 8 x 8 – 8)
c) (36 – 4 x 9) : (3 x 5 x 7 x 9 x 11)
d) (27 – 3 x 9) : 9 x 1 x 3 x 5 x 7
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 biết
a)x+1/2=3/5
b)x*6/7=5/21
c)x:4/3=8/9
Tìm x;
(x+9)+(x-2)+(x+7)+(x-4+(x+5)+(x-6+(x+3)+(x-8)+(x+1)=95
câu 8 : tìm x
3/5 : x = 3
câu 9
a) 1/5 + 4/11 + 4/5 + 7/11
b) 5/6 + ( 5/9 - 1/4 )
