Question

Tìm X, biết:
a) 2022 x X + 3 = 4047               b) 3 x ( X - 4/3 ) = 1/6

Answer 1

a: =>2022x=4044

hay x=2

b: =>(x-4/3)=1/18

hay x=1/18+4/3=1/18+24/18=25/18

Answer 2

`a) 2022 xx x+3=4047`

`2022 xx x=4047-3`

`2022 xx x=4044`

`x=4044:2022`

`x=2`

`b) 3 xx(x- 4/3)=1/6`

`x-4/3=1/6:3`

`x-4/3=1/6xx1/3`

`x-4/3=1/18`

`x=1/18+4/3`

`x=1/18+24/18`

`x=25/18`

Answer 3

`2022 xx x + 3 = 4047`

`2022 xx x = 4047 - 3`

`2022 xx x = 4044`

`x = 4044 : 2022`

`x = 2`

__________________________________

`3 xx (x - 4/3) = 1/6`

`x - 4/3 = 1/6 : 3`

`x - 4/3 = 1/6 xx 1/3`

`x - 4/3 = 1/18`

`x = 1/18 + 4/3`

`x = 25/18`
