b) x=232. mình nhầm ^^

b, x =232 nha

a) x-36:18=12

    x-2=12

    x=12+2

    x=14

b)(x-36):18=12

x-36=216

x=216+36

x=252

b,, ( x - 36 ) : 18 = 12

    x - 36       = 12 x 18

    x - 36       =      2016

    x             = 2016 + 36 

    x            =       2052

a, x - 36 : 18 = 12

    x - 2         = 12

         x         = 12 + 2

          x        = 14

b, (  x - 36 ) : 18 = 12

      x - 36           = 12 . 18

      x - 36           = 216

           x             = 216 + 36

            x            = 252

a) x - 36 : 18 = 12

             x - 2 = 12

             x       = 12 + 2

             x       = 14

a) x-36:18=12

x-2=12

x=12+2

x=14

b) (x-36):18=12

x-36=12.18

x-36=216

x=216+36

x=252

a, x - 36 : 18 = 12

x - 2 = 12

x = 12 + 2

x = 14

b, (x - 36) : 18 = 12

x - 36 = 12 x 18

x - 36 = 216

x = 216 + 36

x = 252

1) \(x-36:18=12\)

\(\Rightarrow x-2=12\)

\(\Rightarrow x=14\)

2) \(\left(x-36\right):18=12\)

\(\Rightarrow x-36=216\)

\(\Rightarrow x=252\)

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

Chúc bạn học tốt!!!

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

\(x-1=0:12\)

\(x-1=0\)

\(x=0+1\)

\(x=1\)

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

\(x-47=0+115\)

\(x-47=115\)

\(x=115+47\)

\(x=162\)

\(c.x-36:18=12\)

\(x-36=12.18\)

\(x-36=216\)

\(x=216+36\)

\(x=216+36\)

\(x=252\)

a) 12 . ( x - 1 ) = 0

x - 1 = 0 : 12

x - 1 = 0

x = 0 + 1

x = 1

b) ( x - 47 ) - 115 = 0

x - 47 = 0 + 115

x - 47 = 115

x = 115 + 47

x = 162

c) x - 36 : 18 = 12

x - ( 36 : 18) = 12

x - 2 = 12

x = 12 + 2

x = 14

d) (x - 36) : 18 = 12

x - 36 = 12 . 18

x - 36 = 216

x = 216 + 36

x = 252

a)  x - 36 : 8 = 12

     x - 2        = 12

     x             = 12 + 2

     x             = 14

b.= 252 nha .chúc bạn học tốt

vukieulinhdan

a) x - 36 : 8 = 12

x - 2 = 12

x = 12 + 2

x = 14 

\(x-36:18=12\)

\(\Leftrightarrow x-2=12\)

\(\Leftrightarrow x=12+2\)

\(\Leftrightarrow x=14\)

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

         146 - x       = 401 - 315

              146 - x = 86

                      x = 146 - 86

                     x  = 60

x - 36 : 18 = 12

  x - 2       = 12

          x   = 12 + 2

         x    = 14

( x - 36 ) : 18 = 12

x - 36           = 216

              x    = 216 + 36

              x   = 252

**** cho mình nha! Cảm ơn bạn!

315+(146-x)=401
