a ) X x 6 - 4,99 = 25,01 b ) X : 6 = 7/4
X x 6 = 25,01 + 4,99 X : 6 = 1,75
X x 6 = 30 X = 1,75 x 6
X = 30 : 6 X = 10,5
X = 5
a) \(6x-4,99=25,01\)
\(6x=25,01+4,99\)
\(6x=30\)
\(x=5\)
vậy \(x=5\)
b) \(\frac{x}{6}=\frac{7}{4}\)
\(\Rightarrow4x=6.7\)
\(\Rightarrow4x=42\)
\(\Rightarrow x=10,5\)
vậy \(x=10,5\)
a) x*6-4,99=25,01
=>x*6=25,01+4,99
=>x*6=30
=>x=30:6
=>x=5
Vậy x=5
