`575-(6x+70)=445`
`=> 6x+70=575-445`
`=> 6x+70=130`
`=>6x=130-70`
`=>6x=60`
`=>x=60:6`
`=>x=10`
Vậy: `x=10`
`575- (6x+70)= 445`
`6x+70=130`
`6x=60`
`x= 60/6`
`x=10`
Vậy `x=10`

3x-8=269
X x 13 = 39
( x - 15 ) - 75 = 0
6x - 39 = 201
575 - ( 6x +70 ) = 445
(x – 15 ) – 75 = 0 b) 575- (6x +70) =445
c) x –105 : 21 =15 d) (x - 105) :21 = 15
Tìm x, biết
a) 575 – (6X + 70) = 445
b) (32.15) : 2 = (X +70) : 14 – 40
c) (X – 15) -75 = 0 d) 420 + 65.4 = (X + 175):5 +30
e) X – 4867 = (175.2050.70) : 25 + 23 f) [(X + 32) -17].2 = 42
g) 96 – 3.(X+1)=42 h) 165 – 19.(35 : X + 3) = 13
a.575-(6x+70)=445
b.(3-X)x(X-3)=0
giải thích hộ mình nha...cảm ơn mọi ng
575-(6.x+70)=445
tìm xEN biết :
a) ( x - 15 ) - 75 = 0
b) 575 - ( 6x + 70 ) = 445
c) 315 + ( 125 - x ) = 435
giúp mk nhé mn ơi
Tìm x
a) ( x - 15 ) - 15 = 0
b) 575 - ( 6x + 70 ) = 445
c) 315 + ( 125 - x ) = 435
d) x - 105 : 21 = 15
a/(x-15)-75=0
b/575-(6x+70)=445
c/315+(125-x)=435
d/x-105:21=15
e/(x-105):21=1
