\(2.x+6=96\)
\(\Rightarrow2x\) \(=96-6\)
\(\Rightarrow2x\) \(=90\)
\(\Rightarrow x\) \(=90:2\)
\(\Rightarrow x\) \(=45\)
Vậy \(x=45\)
2 . x + 6 = 96
2 . x = 96 - 6
2 . x = 90
x = 90 : 2 = 45
\(2.x+6=96\)
\(\Rightarrow2x=90\)
\(\Rightarrow x=90:2\)
\(\Rightarrow x=45\)
2 . x + 9 = 96
2x = 96-6
2x = 90
x = 90 : 2
x = 45
