Question

6-(3x+1)=(1-x)

Answer 1

\(\Rightarrow6-3x-1=1-x\Rightarrow-3x+5=1-x\Rightarrow3x-x=5-1\Rightarrow2x=4\Rightarrow x=2\)

 

Answer 2

  6-(3x+1)=(1-x)

=> 3x + 1 = 6- 1+ x

=> 3x - x = 6 - 1 - 1

=> 2x = 4

=> x = 2

Vậy x = 2

Chúc bạn học tốt! 

Answer 3

6 - (3x+1) = (1-x)

⇒ 6 - 3x - 1 = 1 - x

⇒ -3x + x = 1 + 1 - 6

⇒ -2x = -4

⇒ x = 2

Vậy...
