3,16 : ( x – 7 ) : 8 = 2 3,16 : ( x – 7 ) = 2 x 8 3,16 : ( x – 7 ) = 16 x – 7 = 3,16 : 16 x – 7 = 0,1975 x = 0,1975 + 7 x = 7,1975 Trả lời
`#DyHungg` `3,16:(x-7):8=2` `⇒3,16:(x-7)=8xx2` `⇒3,16:(x-7)=16` `⇒(x-7)=3,16:16=0,1975` `⇒x-7=0,1975` `⇒x=0,1975+7` `⇒x=7,1975` Trả lời
3,16 : ( x – 7 ) : 8 = 2
3,16 : ( x – 7 ) = 2 x 8
3,16 : ( x – 7 ) = 16
x – 7 = 3,16 : 16
x – 7 = 0,1975
x = 0,1975 + 7
x = 7,1975
