Question

x-2/3=x+1/4

Answer 1

\(x-\dfrac{2}{3}=x+\dfrac{1}{4}\Leftrightarrow0=\dfrac{1}{4}+\dfrac{2}{3}=\dfrac{11}{12}\)vo li 

Vay pt vo nghiem 

Answer 2

\(\dfrac{x-2}{3}\)=\(\dfrac{x+1}{4}\)

=> (x - 2) . 4 = (x + 1) . 3

=> 4x - 8 = 3x + 3

=> 4x - 3x = 3 + 8

=> x = 11

Answer 3

x- \(\dfrac{2}{3}\) = x+\(\dfrac{1}{4}\)

12. ( x - \(\dfrac{2}{3}\) ) = 12 . ( x + \(\dfrac{1}{4}\) )

4 . (x-2) = 3. (x+1) 

4 . x - 8 = 3. |(x+1)|

4 . x - 8=3x + 3

4 . x - 8 = 3 . x + 3 + 8

4 . x = 3 . x + 11

4 . x - 3 . x = 3 . x + 11 - 3 . x

1. x = 3 . x + 11 - 3 . x

x = 3 . x + 11 - 3 . x

VẬY x = 11

Answer 4

x−23=x+14𝑥−23=𝑥+14

=> 4 x (x-2) = 3 (x+1)

=> 4x-8=3x+3

=> x=11

Answer 5

x+14𝑥+14

=> (x - 2) . 4 = (x + 1) . 3

=> 4x - 8 = 3x + 3

=> 4x - 3x = 3 + 8

=> x = 11
