Tìm y
\(\dfrac{2}{5}\) X y : \(\dfrac{7}{4}=\dfrac{7}{8}\)
2\(\dfrac{2}{5}\) : y x 1\(\dfrac{1}{4}\) = 2\(\dfrac{3}{5}\)
\(\dfrac{12}{5}-1\dfrac{2}{5}x\) y = 1\(\dfrac{1}{4}\)
y+y x3/2+y:2/7=720
y + y x 4,5 : 3 + y x 7 : 2 =2 25
Các bạn giúp mình nha!
Tìm X và Y:
1. 1/2 + 1/6 x X = 9/2
2. 10/3 - 2/5 : Y = 2/7
3. 32/5 - Y : 2/3 = 1/2
4. 1/5 + 1/7 x Y = 9/8
y+y*1/3:2/9+y:2/7=252
y + y x 1/3 : 2/9 + y : 2/7 =252 . tim y
tìm y
y x 2/7 +y : 7/5 =1,2
TÌM y :
y + y . 1/3 : 2/9 + y : 2/7 = 252
2/5* y + y * 1/5 =2/7
tìm y biết
2/3 : y/9 : 7/5 = 2/7 : 3/5 : 10/9
