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

Ai thấy đúng cho mk nhé
5x-x=29-36/4
=>x*(5-1)=29-9
=>x*4=20
=>x=20:4
=>x=5

tim so tu nhien x , biet
a, 5x - x = 29 - 36 : 4
b, ( 3x - 48 ) . 6 = 3 mu 3 . 2 mu 2 + 2 mu 3 . 3 mu 2 - 12 mu 2
c, x thuoc B(6) va 22 < x < hoac = 36
a) \(\Leftrightarrow4x=20\Leftrightarrow x=5\)
b) \(\Leftrightarrow18x-288=27.4+8.9-144\)
\(\Leftrightarrow18x=108+72-144+288=324\)
\(\Leftrightarrow x=18\)
c)Ta có:
\(x\in B\left(6\right)\) và \(22< x\le36\)
mà \(B\left(6\right)=\left\{0;6;12;18;24;30;36;42;48;...\right\}\)
\(\Rightarrow x\in\left\{0;6;12;18;24;30;36;42;48;...\right\}\) và \(22< x\le36\)
\(\Rightarrow x\in\left\{24;30;36\right\}\)
Vậy \(x\in\left\{24;30;36\right\}\)
Tìm x
a) 5x - x = 29 - 36 :4 b) (3x -48) . 6 = 33.22+23.32 -122
a, 5x - x = 29 - 36 : 4
=> 4x = 29 - 9
=> 4x = 20
=> x = 5
vậy_
b, (3x - 48).6 = 33.22 + 23.32 - 122
=> (3x - 48).6 = 9.4 + 8.9 - 144
=> (3x - 48).6 = 36 + 72 - 144
=> (3x - 48).6 = 36
=> 3x - 48 = -6
=> 3x = 42
=> x = 14
vậy_
