76,22 - y *3 = 30,61 *2
76,2 - y *3 = 61,22
y *3= 76,2-61,22
y *3=14,98
y= 14,98 :3
y=4,99
76,22 - y x 3 = 30,61 x 2
\(76,22-y\times3=30,61\times2\\ \Rightarrow76,22-y\times3=61,22\\ \Rightarrow y\times3=76,22-61,22\\ \Rightarrow y\times3=15\\ \Rightarrow y=15:3\\ \Rightarrow y=5\)
2. Tìm y
a) y : 15 - 34,87 = 52,21 + 6
b) 76,22 - y x 3 = 30,61 x 2
76,22 -y *3= 30,61 *2

\(76,22-y\times3=61,22\)
\(y\times3=76,22-61,22\)
\(y\times3=15\)
\(x=15:3\)
\(x=5\)
76,22 - y * 3 = 30,61 * 2
76,22 - y * 3 = 61,21
76,22 - y = 61,22 : 3
76,22 - y = 20/61/150
y = 76,21 - 20/61/150
y = 55/241/300
\(76,22-y\times3=30,61\times2\)
\(\Leftrightarrow\)\(76,22-y\times3=61,22\)
\(\Leftrightarrow\)\(y\times3=76,22-61,22\)
\(\Leftrightarrow\)\(y\times3=15\)
\(\Leftrightarrow\)\(y=15\div3\)
\(\Leftrightarrow\)\(y=5\)
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 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 \(y=5\)

Ai giúp mk thì mk cho like nha
__Cảm ưn__
76,22 - y x 3 = 30,61 x 2
76,22 - y x 3 = 61,22
y x 3 = 76,22 - 61,22
y x 3 = 15
y = 15 : 3
y = 5
HT và $$$
76,22 - y x 3 = 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 ( ?! )
