y:8 + y x25%= 3/2023

Đáp án + Giải thích các bước giải:

`y:8+yxx25%=3/2023`

Cách `1:`

`=>y:8+yxx25/100=3/2023`

`=>yxx1/8+yxx1/4=3/2023`

`=>yxx(1/8+1/4)=3/2023`

`=>yxx(1/8+2/8)=3/2023`

`=>yxx3/8=3/2023`

`=>y=3/2023:3/8`

`=>y=3/2023xx8/3`

`=>y=8/2023`

Cách `2:`

`=>y:8+y:4=3/2023`

`=>y/8xx16184+y/4xx16184=3/2023xx16184`

`=>2023xxy+4046xxy=24`

`=>(2023+4046)xxy=24`

`=>6069xxy=24`

`=>y=24:6069`

`=>y=24/6069=8/2023`

`Vậy` `y=8/2023`
