Tim y:

2. Tìm y
a) y : 15 - 34,87 = 52,21 + 6
b) 76,22 - y x 3 = 30,61 x 2
A) y:15-34,87=52,21+6
B)76,22-y×3=30,61×2
y:15 - 34,87=52,21+6
y:15 =52,21+6+34,87
y:15 =93.08
y=1396.2
b) tự làm . tính ra rồi chuyển zế là đc
A) y:15-34,87=52,21+6
<=>y:15-34,87=58,21
<=>y:15=93,08
<=>y=1396,2
Vậy y=1396,2
B)76,22-y×3=30,61×2
<=>76,22-yx3=61,22
<=>yx3=15
<=>y=5
Vậy y=5
a) y:15-34,87=52,21+6
y:15-34,87=58,21
y:15=58,21+34,87
y:15=93,08
y=93,08 x 15
y=1396,2
b) 76,22-y×3=30,61×2
76,22-y x3=61,22
y x 3 = 76,22-61,22
y x 3 = 15
y = 15 : 3
y = 5
a) y : 15 - 34,87= 52,21 + 6 b) 76,22 = y x 3 = 30,61 x 2
a) y / 15 - 34,87 = 52,21 + 6
y / 15 - 34,87 = 58,21
y / 15 = 58,21 + 34,87
y / 15 = 93,08
y = 93,08 * 15 = 1396,2
b) 76,22 = y * 3 = 30,61 * 2
76,22 = y * 3 = 61,22
=> 76,22 = 61,22 ( ?! )
Sai đề
a) y : 15 - 34,87= 52,21 + 6 b) 76,22 = y x 3 = 30,61 x 2
a) y : 15 - 34,87 = 52,21 + 6 ( tui biet moi cau a thoi)
y : 15 - 34,87 = 58,21
y : 15 = 58,21 - 34,87
y : 15 = 23.34
y = 351

-Bạn nguyễn minh thu làm đúng rồi nhé ~!
Hok tốt
nhé bạn
y : 15 - 34,87 = 52,21 + 6 76,22 - y x 3 = 30,61 x 2
mn giải giúp mik nhé thanks bạn rất nhùi
y : 15 - 34,87 = 52,21 + 6 76,22 - y x 3 = 30,61 x 2
y : 15 - 34,87 = 58,21 76,22 - y x 3 = 61,22
y : 15 = 58,21 + 34,87 y x 3 = 76,22 - 61,22
y : 15 = 93,08 y x 3 = 15
y = 93,08 x 15 y = 15 : 3
y = 1396,2 y = 5
a y bằng 1396,2
b y bằng 5
mình không nêu rõ cách làm thông cảm

(Giai chi tiet nhe!)
a y :15 -34,87 =52,21+6
b 76,22-y nhân 3 =30,61 nhân 2
a) \(\frac{y}{15}-34,87=52,21+6\)
\(\frac{y}{15}=58,21+34,87\)
\(\frac{y}{15}=93,08\)
\(\Rightarrow y=93,08.15\)
\(\Rightarrow y=1396,2\)
vậy \(y=1396,2\)
b) \(76,22-3y=30,61.2\)
\(76,22-3y=61,22\)
\(3y=76,22-61,22\)
\(3y=15\)
\(y=5\)
vậy \(y=5\)
Tìm X :
a) X : 15 - 34,87 = 52,21 + 6 b) 76,22 - X x 3 = 30,61 x 2
b) 76,22 - X x 3 = 30,61 x 2
76,22 - X x 3= 61.22
X x 3= 76,22 -61.22=15

a) X : 15 - 34,87 = 52,21 + 6
