Tìm x : X x 1/3+X:3/5=8 Tìm x dùm mình cảm ơn 27/11/2021 Bởi Eva Tìm x : X x 1/3+X:3/5=8 Tìm x dùm mình cảm ơn
` x × 1/3 + x : 3/5 = 8 ` ` => x × 1/3 + x × 5/3 = 8 ` ` => x × (1/3 + 5/3) = 8 ` ` => x × 6/3 = 8 ` ` => x × 2 = 8 ` ` => x = 8 : 2 ` ` => x = 4 ` Vậy ` x = 4 ` Bình luận
`x×1/3+x÷3/5=8`
`x×1/3+x×5/3=8`
`x×(1/3+5/3)=8`
`x×2=8`
`x=8÷2`
`x=4`
Vậy `x=4`
` x × 1/3 + x : 3/5 = 8 `
` => x × 1/3 + x × 5/3 = 8 `
` => x × (1/3 + 5/3) = 8 `
` => x × 6/3 = 8 `
` => x × 2 = 8 `
` => x = 8 : 2 `
` => x = 4 `
Vậy ` x = 4 `
