Tìm x biết:
5x - x = 29 - 36 : 4
Tìm x biết
5x-x=29-36:4
5x-x=29-36:4
4x =20
x =20:4
x =5
Vậy x=5
5x-x=29-36:4
<=>4x=29-36:4
<=>4x=29-9
<=>4x=20
<=>x=5
Vậy...bla bla
\(5.x-x=29-36:4\)
\(5.x-x=29-9\)
\(5.x-x=20\)
\(5.x-x.1=20\)
\(\Rightarrow x.\left(5-1\right)=20\)
\(x.4=20\)
\(\Rightarrow x=5\)
Tìm x biết:
5x-x=29-36:4
5x-x - 29+ 9 bằng 0
4x-18 bằng 0
4x bằng 18
x bằng \(\frac{9}{2}\)
5x - x = 29 - 36 : 4
5x - x = 29 - 9 = 20
4x = 20
x = 20 : 4
x = 5
Tìm x biết:
5x - x = 29 - 36 :3
5x - x = 29 - 36 : 3
4x = 29 - 36 : 3
4x = 29 - 12
4x = 17
x = 17 : 4
x = 4,25
5x-x=29-36/4
5x - x = 29 - \(\frac{36}{4}\)
5x - x = 29 - 9
5x - x = 20
4x = 20
x = 20 : 4
x = 5
Ai thấy đúng cho mk nhé
5x-x=29-36/4
=>x*(5-1)=29-9
=>x*4=20
=>x=20:4
=>x=5
5x−x=29−36:4
5x-x=29-9
5x-1x=25
(5-1)x=25
4x=25
x=25:4
x=6,25
5x - x = 29 - 36 : 4
5x - x = 29 - 9
5x - 1x = 20
(5 - 1)x = 20
4x = 20
x = 20 : 4 = 5
5x-x=29-36:4 mong bạn ghi rõ câu trả lời cho mk nha
\(4x=29-9\Leftrightarrow4x=20\Leftrightarrow x=20:5\Leftrightarrow x=4\)

x − 103 = − 203 ; x − − 36 = 0 ; x − 105 = − 150 ; x − − 21 = − 29.
Tìm x biết
x − 103 = − 203 ; x − − 36 = 0 ; x − 105 = − 150 ; x − − 21 = − 29.
tìm x bt
5^x - x = 29-36 :4
5X-X=29-9
5x-x=20
5x-1x=20
4x=20
x=20:4=5
vậy x = 5
