\(a,243\times x=76545\\ \Rightarrow x=76545:243\\ \Rightarrow x=315\\ b,97328:x=316\\ \Rightarrow x=97328:316\\ \Rightarrow x=308\)
Bài 4:Tìm x:
a) 243 x x =76545 b) 97328 : x = 316
Bài 2. Tìm x:
a/ x + 456788 = 9867655 b/ x – 23345 = 9886 c/ 283476 + x = 986352

Bài 2: Tìm X:
a) X x 12 + X x 7+ X = 100 c) (X- 60720) : 5= 318 + 642
b) X x 4 + X x 3 = 7497 :7 d) X : 4 + 11250 = 22850
Giải gấp cho em với ạ
Tìm x:
a) 3/4 x X = 5/8

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
Tìm x:
a)x+3/4=5/3
b)x-2/3=7/2
Tìm x:
a. 246 : x + 34 : x = 5 b. 360 : x – 126 : x = 6
Tìm x:
a. 1337 + 13 x x = 6745 b. 142 x x – 41 x x – x = 408000
