bài 1 tìm y biết :
a) y -32,15 x 6 = 54,76 b) 245,716 - y x 12 = 76,54
a) y - 32,15 x 6 = 54,76
=> y - 192,9 = 54,76
y = 54,76 + 192,9
y = 247,66
b) 245,716 - y x 12 = 76,54
=> y x 12 = 245,716 - 76,54
y x 12 = 169,176
=> y = 169,176 : 12
y = 14,098

a, y - 32,15 x 6 = 54,76
y - 192,9 = 54,76
y = 54,76 + 192,9
y = 247,66
Vậy y = 247,66
b, 245,716 - y x 12 = 76,54
