a) x + 5,28 =9,19 b)tự học nhé neko bye
x=9,19-5,28
x=3,91
a) \(x+5,28=9,19\)
\(x=9,19-5,28\)
\(x=3,91\)
b) \(x+37,66=80,84\)
\(x=80,84-37,66\)
\(x=43,18\)
c) \(x-34,87=58,21\)
\(x=58,21+34,87\)
\(x=93,08\)
d) \(76,22-x=38,08\)
\(x=76,22-38,08\)
\(x=38,14\)
a) x + 5, 28 = 9, 19
x = 9, 19 - 5, 28
x = 3, 91
b) x + 37, 66 = 80, 84
x = 80, 84 - 37, 66
x = 43, 18
c) x - 34, 87 = 58, 21
x = 58, 21 + 34, 87
x = 93, 08
d) 76, 22 - x = 38, 08
x = 76, 22 - 38, 08
x = 38, 14
a, x + 5,28 = 9,19 c, x - 34,87 = 58,21
<=> x = 9,19 - 5,28 <=> x = 58,21 + 34,87
<=> x = 3,91. Vậy x = 3,91 <=> x = 93,08. Vậy x = 93,08
b, x + 37,66 = 80,84 d, 76,22 - x = 38,08
<=> x = 80,84 - 37,66 <=> x = 76,22 - 38,08
<=> x = 43,18. Vậy x = 43,18 <=> x = 38,14. Vậy x = 38,14
