Tìm x
x - 4368 = 3484 x 4
x-4368=3484*4
a) Tìm X: X - 4368 = 3484 x 4
b) Tính bằng cách thuận tiện nhất 49 x 385 – 39 x 385
Tìm x:
X x 2/5 = 4/15

x x 2 + x x 3 + x x 4 + x = 2130
tìm x:
x :7/11 = 22
11/2 - 3/2 x X = 7/4
tìm x:
x : 33 = \(\dfrac{9}{66}\) \(\dfrac{4}{5}\) x \(x\) = \(\dfrac{10}{11}\) :\(\dfrac{3}{4}\)
