Question

`2x-1/3=-3/4`

`7,3-2x=3,5`

Answer 1

a: =>2x=-3/4+1/3=-9/12+4/12=-5/12

=>x=-5/24

b: =>2x=7,3-3,5=3,8

hay x=1,9

Answer 2

`2x - 1/2 = -3/4`

` 2x = -3/4 + 1/2`

` 2x = -5/12`

` x = -5/12 : 2`

` x = -5/12 xx 1/2`

` x = -5/24`

 

` 7,3 - 2x = 3,5`

` 2x = 7,3 - 3,5`

` 2x = 3,8`

` x = 3,8 : 2`

` x = 1,9`
