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
x - 36 : 18 = 12
x - 2 = 12
x= 14
(x - 36) : 18 = 12
(x - 36) = 216
x = 216 + 36
x = 352
461 + (x - 45) = 387
461 + x - 45 = 387
x = 387 - 461 + 45
x = -29
(x-36):18=12
x-36=12x18
x-36=216
x=216+36
x= 252
x-36:18=12
x-2=12
x=14
461+(x-45)=387
x-45= 387 - 461
x-45=-74
x=-74+45
x=-29
\(x-36:18=12\) \(\left(x-36\right):18=12\)
\(x-36=12.18\) \(x-36=12.18\)

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) 0 : x = 0
x = 0 : 0
x = 0
b ) x - 36 : 18 = 12
x - 2 = 12
x = 12 + 2
x = 14
c ) ( x - 36 ) : 18 = 12
( x - 36 ) = 12 x 18
( x - 36 ) = 216
x - 36 = 216
x = 216 - 36
x = 180
b) x - 36 : 18 = 12
x - 2 = 12
x = 12 + 2
x = 14
c) (x - 36) : 18 = 12
x - 36 = 12 x 18
x - 36 = 216
x = 216 + 36
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, \(\left(x-36\right):18=12\Rightarrow x-36=216\Rightarrow x=252\)
