(6x - 39) : 3 = 201
6x - 39 = 201 x 3
6x - 39 = 603
6x = 603 + 39
6x = 642
x = 642 : 6
x = 107
23 + 3x = 56 : 53
23 + 3x = 56-3
23 + 3x = 125
3x = 125 - 23
3x = 102
x = 102 : 3
x = 34
\(\left(6x-39\right):3=201\Rightarrow6x-39=101.3\Rightarrow6x=303+39\Rightarrow x=342:6=57\)
Vậy x = 57
\(23+3x=5^6:5^3\Rightarrow23+3x=125\Rightarrow3x=125-23\Rightarrow x=102:3\Rightarrow x=34\)
Vậy x = 34
k nhaaa
a) [6x - 39 ] : 3 = 201
6x - 39 = 201.3
6x - 39 = 603
6x = 603+ 39
6x = 642
x = 642 : 6
x = 107
Vậy x = 107
b) 23 + 3x = 56 : 53
23 + 3x = 125
3x = 125 - 23
3x = 102
x = 102 : 3
x = 34
Vậy x = 34
A,(6x-39)= 201 .3
(6x -39)= 603
6x = 603+39
6x = 642
x =107
B= 23+3x = 56-3
23 +3x = 53
23+3x = 125
3x = 125 - 23
3x = 102
x= 102 : 3
x =34
Nhớ k cho mình nhé
