Tìm y biết y + y x 1/3 : 2/9 + y : 2/7 = 252
nếu mà bạn giải xong rồi thì bạn nói cho mình biết nhen
y + y x y x 1/3 : 2/9 + y : 2/7 = 252
(4/5 : 6/5 + 1/5 : 1/y) x 30 - 26 += 54
y+y*1/3:2/9+y:2/7=252
TÌM y :
y + y . 1/3 : 2/9 + y : 2/7 = 252
\(y+y.\frac{1}{3}:\frac{2}{9}+y:\frac{2}{7}=252\)
=>\(y.\frac{2}{2}+y.\frac{3}{2}+y.\frac{7}{2}=252\)
=>\(y.\left(\frac{2}{2}+\frac{3}{2}+\frac{7}{2}\right)=252\)
=>\(y.6=252\)
=>y=252:6
