k mik nhak tặng nè

\(\left(a\right)x-36\div18=12\)

\(x-2=12\)

\(x=12+2\)

\(x=14\)

\(\text{Đảm bảo đúng! mình học rồi!}\)

\(x-36:18=12\)

\(\Leftrightarrow x-2=12\)

\(\Leftrightarrow x=12+2\)

\(\Leftrightarrow x=14\)

Vậy \(x=14\)

\(\left(x-36\right):18=12\)

\(\Leftrightarrow x-36=12.18\)

\(\Leftrightarrow x=12.18+36\)

\(\Leftrightarrow x=216+36\)

\(\Leftrightarrow x=252\)

Vậy \(x=252\)

a) x - 36 : 18 = 12

=> x - 2 = 12

=> x = 12 + 2

=> x = 14

Vậy x = 14

b) (x - 36) : 18 = 12

=> x - 36 = 12 . 18

=> x - 36 = 216

=> x = 216 + 36

=> x = 252

Vậy x = 252

x - 36 : 18 = 12

-> x - 2 = 12

-> x = 14

( x - 36 ) : 18 = 12

-> ( x - 36 ) = 12 . 18

-> ( x - 36 ) = 216

-> x = 216 + 36

-> x = 252

315 +  ( 146 - x ) = 401

sai đề hay sao ấy,bạn đánh lại đi

tick nhé

a, \(12\left(x-1\right)=0\Rightarrow x-1=0\Rightarrow x=1\)

b, \(\left(x-47\right)-115=0\Rightarrow x-47-115=0\)

\(\Rightarrow x=115+47=162\)

c, \(x-36:18=12\Rightarrow x-2=12\Rightarrow x=14\)

d, \(\left(x-36\right):18=12\Rightarrow x-36=216\Rightarrow x=252\)
