Toán tìm X biết X x 4 + 4/5 = 17/6- 2/5 ( hộ mik gấp ạ,mik đang cần gấp ) 17/07/2021 By Emery tìm X biết X x 4 + 4/5 = 17/6- 2/5 ( hộ mik gấp ạ,mik đang cần gấp )
`x` x 4 + `4/5` = `17/6` – `2/5` `x` x 4 + `4/5` = `73/30` `x` x 4 = `73/30` – `4/5` `x` x 4 = `49/30` `x` =`49/30` : 4 `x` = `49/120` Trả lời
`x xx 4 + 4/5 = 17/6 – 2/5` `x xx 4 + 4/5 = 73/30` `x xx 4 + 4/5 = 73/30 – 4/5` `x xx 4 = 49/30` `x = 49/30 : 4` `x = 49/120` Trả lời
`x` x 4 + `4/5` = `17/6` – `2/5`
`x` x 4 + `4/5` = `73/30`
`x` x 4 = `73/30` – `4/5`
`x` x 4 = `49/30`
`x` =`49/30` : 4
`x` = `49/120`
`x xx 4 + 4/5 = 17/6 – 2/5`
`x xx 4 + 4/5 = 73/30`
`x xx 4 + 4/5 = 73/30 – 4/5`
`x xx 4 = 49/30`
`x = 49/30 : 4`
`x = 49/120`
