Question

5x-(39-x)=3¹¹:3⁰ 

Answer 1

`5x-(39-x)=3^11:3^0`

`=>5x-39+x=3^(11-0)`

`=>x*(5+1)-39=3^11`

`=>6x-39=3^11`

`=>6x=39+3^11`

`=>x=(39+3^11)/6`

`=>x=(13+3^10)/2`

Vậy: ... 

Answer 2

5x - (39 - x) = 3¹¹ : 3⁰

=> 5x + x - 39 = 3¹¹

=> 6x              = 177 147 + 39

=>   x              = 177 186 : 6

=>   x              = 29 531
