2 câu trả lời
`a)362 -96:y=356`
`⇔96:y=6`
`⇔y=16`
`b) 7×y+398=496`
`⇔7×y=98`
`⇔y=14`
`c) 236+y:6=325`
`⇔y:6=89`
`⇔y=543`
`a) 362 -96:y=356`
`96 : y = 362 - 356`
`96 : y = 6`
`y = 96 : 6`
`y = 16`
`b) 7 \times y + 398 = 496`
`7 \times y = 496 - 398`
`7 \times y = 98`
`y = 98 : 7 `
`y = 14`
`c) 236 + y :6 = 325`
`y : 6 = 325 - 236`
`y : 6 = 89`
`y = 89 \times 6`
`y = 534`
