35.(24 - 6.x)= 0
24-6.x=35: 0
24-6.x=0
-6.x=0-24
-6.x= -24
x=-24 : -6
x=4
vậy x=4
3.(x + 7) -15=27
3.(x+7)=27+15
3.(x+7)=42
x+7= 42:3
x+7=14
x=14-7
x=7
vậy x=7

35 . ( 24 - 6 . x ) = 0
24 - 6 . x = 0 : 35
24 - 6 . x = 0
6 . x = 24 - 0
6 . x = 24
x = 24 : 6
x = 4
3 . ( x + 7 ) - 15 = 27
( x + 7 ) - 15 = 27 : 3
( x + 7 ) - 15 = 7
x + 7 = 7 + 15
x + 7 = 22
x = 22 - 7
x = 15
