a) `x/75=5` `⇒x=5.75=375` b) `(x+74)-318=200` `⇒x-244=200` `⇒x=200+244=444` c) `3636/(12x-91)=36` `⇒36(12x-91)=3636` `⇒12x-91=101` `⇒12x=192` `⇒x=192/12=16` Trả lời
Giải thích các bước giải:
`x / 75 = 5`
`=>x=5.75=375`
`( x +74) – 318 = 200`
`=>x+74=518`
`=>x=444`
`3636 / ( 12 x – 91) = 36`
`=>12x-91=101`
`=>12x=192`
`=>x=16`
a) `x/75=5`
`⇒x=5.75=375`
b) `(x+74)-318=200`
`⇒x-244=200`
`⇒x=200+244=444`
c) `3636/(12x-91)=36`
`⇒36(12x-91)=3636`
`⇒12x-91=101`
`⇒12x=192`
`⇒x=192/12=16`
