(x+3,86)*6=24,36
( x + 3,86 ) nhân 6 = 24,36
tại vì bấm laptop nên ko được tốt lắm thông cảm nha !
giải giúp mình nha !
\(\left(x+3,86\right)\text{ x }6=24,36\)
\(\left(x+3,86\right)=24,36\text{ : }6\)
\(\left(x+3,86\right)=4,06\)
\(x=4,06-3,86\)
\(x=0,2\)
\(\left(x+3,86\right)\times6=24,36\)
\(x+3,86=24,36\div6\)
\(x+3,86=4,06\)
\(x=0,2\)
( x + 3,8 ) x 6 = 24,36
8,64 : ( 1,46+3,34 ) +6,32
(x+3,8) .6 = 24,36
=> (x+3,8)=24,36 : 6
(x+3,8)= 4,06
x= 4,06 - 3,8
x=0,26
8,64 : ( 1,48 + 3,34 ) + 6,32 bai nay sai so r
(x + 3,8) x 6 = 24,36 8,64: (1,48+3,34)+6,32 x + 3,8 = 24,36 = 8,64 : 4,82+ 6,32 x + 3,8 = 4,06 = 1,79253112+6,32 x = 4,06 - 3,8 = 8,11253112 x = 0,26
24,36 chia 6
24,36 : 6 = ... ?

Đặt tính rồi tính
24,36 : 6
24,36 x 0,01
-5,6.x+2,9.x-3,86=-9,8
(-5,6).x + 2,9.x – 3,86 = – 9,8
-2,7x = – 9,8 + 3,86
-2,7x = -5 ,94\(-5,6x+2,9x-3,86=-9,8\\ x\left(2,9-5,6\right)=-9,8+3,86\\ -2,7x=-5,94\\ x=-5,94:\left(-2,7\right)\\ x=2,2\)
-5,6 . x + 2,9 . x - 3,86 = -9,8
(-5,6 + 2,9) . x = -9,8 + 3,86
-2,7x = -5,94
x = -5,94 : -2,7
x = 2,2
(-5,6).x+2,9.x-3,86=-9,8
\(\left(-5,6\right)\cdot x+2,9\cdot x-3,86=-9,8\)
\(=x\left(-5,6+2,9\right)-3,86=-9,8\)
\(=x\cdot\left(-2,7\right)-3,86=-9,8\)
\(\Rightarrow x\cdot\left(-2,7\right)=-9,8+3,86=-5,94\)
\(\Rightarrow x=-5,94:\left(-2,7\right)=2,2\)
\(\Rightarrow x=2,2\)
