100 + 2x = 144
<=> 2x = 144 - 100
<=> 2x = 44
<=> x = 44 : 2
<=> x = 22
100 + 2x = 144
2x = 144 - 100
2x = 44
x = 44 : 2
x = 22
\(100+2x=144\)
\(\Rightarrow2x=144-100\)
\(\Rightarrow2x=44\)
\(\Rightarrow x=44:2\)
\(\Rightarrow x=22\)
Vậy x = 22
_Chúc bạn học tốt_
100 + 2x =144
2x = 144 - 100
2x = 44
x = 44 : 2
x = 22
hok tốt .
100 + 2x = 144
=> 2x = 144 - 100
=> 2x = 44
=> x = 44 : 2
=> x = 22
vậy__
Trả lời:
\(100+2x=144\)
\(\Leftrightarrow\) \(2x=144-100\)
\(\Leftrightarrow\) \(2x=44\)
\(\Leftrightarrow\) \(x=44:2\)
\(\Leftrightarrow\) \(x=22\)
