Question

3(x-2)+2(x-1)=10 

nhanh giúp em với ạ em cảm ơn nhiều

 

Answer 1

=>3x-6+2x-2=10

=>5x=18

hay x=18/5

Answer 2

<=> 3x - 6 + 2x - 2 = 10

<=> (3x + 2x) - (6 + 2) = 10

<=> 5x - 8 = 10

<=> 5x = 18

<=> x = 18/5

Answer 3

`3(x-2) +2(x-1) = 10`

`3x - 6 + 2x - 2=10`

` (3+2)x - (6 + 2) = 10`

` 5x - 8 = 10`

`5x -8 = 10 + 8`

`5x = 18`

`x= 18 : 5`

`x = 18/5`

Answer 4

`3(x-2) + 2(x-1) = 10`

`=> 3x - 3 + 2x - 2 = 10`

`=> (3x + 2x) - (6 + 2) = 10

`=> 5x - 8 = 10`

`=> 5x         = 18`

`=>  x          = 18/5`
