a, \(y-32,15\times6=54,76\)
\(\Leftrightarrow y-192.9=54,76\)
\(\Leftrightarrow y=54,76+192,9\)
\(\Leftrightarrow\)\(y=247.66\)
Vậy ...
b, \(245,716-y\times12=76,54\)
\(\Leftrightarrow y\times12=245,716-76,54\)
\(\Leftrightarrow y\times12=169,176\)

Vậy ...
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 * 6 = 54,76
y- 192,9=54,76
y=247,66
b) 245,716 -y *12=76,54
-y * 12=-169,176
y * 12= 169,176
y=14,098

Y = 247,66 Y= 169,176 : 12
Y=14,098
a) \(y-32,15\times6=54,76\)
\(y-192,9=54,76\)
\(y=54,76+192,9\)
\(y=247,66\)

\(y=14,098\)
a) \(y-32,15\times6=54,76\)
\(\Leftrightarrow y-192,9=54,76\)
\(\Leftrightarrow y=54,76+192,9\)
\(\Leftrightarrow y=247,66\)
Vậy y = 247,66
b) \(245,716-y\times12=76,54\)

Trả lời:
a) \(y-32,15\cdot6=54,76\)
\(y-192,9=54,76\)
\(y=54,76+192,9\)
\(y=247,66\)
b) \(245,716-y\cdot12=76,54\)
\(y\cdot12=245,716-76,54\)
\(y\cdot12=169,176\)
\(y=169,176:12\)
\(y=14,098\)
