5x-x=29-36:4
4x =20
x =20:4
x =5
Vậy x=5

<=>4x=29-36:4
<=>4x=29-9
<=>4x=20
<=>x=5
Vậy...bla bla
\(5.x-x=29-36:4\)
\(5.x-x=29-9\)
\(5.x-x=20\)
\(5.x-x.1=20\)
\(\Rightarrow x.\left(5-1\right)=20\)
\(x.4=20\)
\(\Rightarrow x=5\)
\(5x-x=29-36\text{ : }4\)
\(\Rightarrow4x=29-36\text{ : }4\)
\(\Rightarrow4x=29-9\)
\(\Rightarrow4x=20\)
\(\Rightarrow x=20\text{ : }4\)
\(\Rightarrow x=5\)
5x - x = 29 - 36:4
4x = 29 - 9
x = 20 : 4
x = 5
5x−x=29−36 : 4
⇒4x=29−36 : 4
⇒4x=29−9
⇒4x=20
⇒x=20 : 4
⇒x=5
