x=\(\dfrac{3}{2}-\dfrac{4}{5}=\dfrac{7}{10}\)
a) x + 4/5 = 3/2
x = 3/2 - 4/5
x = 7/10
b) x - 3/2 = 11/4
x = 11/4 + 3/2
x = 17/4
c) 25/3 - x = 5/6
x = 25/3 - 5/6
x = 15/2
Bài 2. Tìm x:
a/ x + 456788 = 9867655 b/ x – 23345 = 9886 c/ 283476 + x = 986352

Bài 4:Tìm x:
a) 243 x x =76545 b) 97328 : x = 316
Tìm x:
a. 246 : x + 34 : x = 5 b. 360 : x – 126 : x = 6
Tìm x:
a) 3/4 x X = 5/8

Tìm x:
a. 1337 + 13 x x = 6745 b. 142 x x – 41 x x – x = 408000
Tìm x:
a)x+5/8=9/3
Tìm x biết aaa : ( x:a ) = 37
Tìm x:
a) x - \(\dfrac{5}{7}\) = \(\dfrac{3}{5}\) x \(\dfrac{1}{2}\) b) x \(x\dfrac{2}{3}=\dfrac{5}{8}+\dfrac{3}{4}\)
Tìm x:
a, x : 2 = \(\dfrac{2}{3}+\dfrac{3}{4}\) b,X x \(\dfrac{1}{5}=1-\dfrac{3}{25}\)
hì mn giải dùm em nha
