Tìm X. a) x × 1,6 = 98. b) 6,38 – x = 1,34 28/11/2021 Bởi Adalynn Tìm X. a) x × 1,6 = 98. b) 6,38 – x = 1,34
`a)` `1,6x=98` `⇔x=98 : 1,6` `⇔x=61,25` Vậy `x=61,25` `b)` `6,38-x=1,34` `⇔-x=1,34-6,38` `⇔-x=-5,04` `⇔x=5,04` Vậy `x=5,04` Bình luận
a) x × 1,6 = 98 b) 6,38 – x = 1,34
x= 98:1,6 x=6,38-1,34
x=61,25 x=5.04
`a)` `1,6x=98`
`⇔x=98 : 1,6`
`⇔x=61,25`
Vậy `x=61,25`
`b)` `6,38-x=1,34`
`⇔-x=1,34-6,38`
`⇔-x=-5,04`
`⇔x=5,04`
Vậy `x=5,04`
