TH1: TH2:
-8(x-3)=24-16:2 -8(-x+3)=24-16:2
-8x+24=16 8x-24=16
-8x=16-24 8x=16+24
-8x=-8 8x=40
x=1 x=5
Vậy \(x\in1;5\)
-8/x-3/=24-16:2 Suy ra x-3=-8;8

2/tim x
4x-15= -75-x
3/tim x thuoc z sao cho 12 chia het cho (x-3)
cac bn giup mk nhe
bai 1)tim x biet
a )24-(36+5)=x
b)14-21=(13-x)-(15+8)
bai 2) tim x biet
a)17-x=-25+(-16+9)
b)3x-21=-19-(-2x)
Tinh gia tri cua phan so: A= 2 x 3 + 2 x 4 x 8 + 4 x 8 x 16 + 8 x 16 x 32/ 3x 4 + 2 x 6 x 8 + 4 x 12 x 16 + 8 x 24 x 32
Bài 1: Tìm x
x-7/12.x=5/24-3/8.x
(x-1/2).(-3-x/2)=0
x-3/-2=-8/x-3
=) (x-3).(x-3)=(-2).(-8)
(x-3) mũ 2 =16
1 ) tim x
A) (19x + 2 .52) : 14 = (13-8)2 - 42
B) 2 . 33 = 10 . 312 . 8 . 274
2) tim x thuoc N
a) 390 - ( x - 7 ) = 169 : 13
c) x - 6 : 2 - ( 48 - 24 ) : 2 : 6 - 3 = 0
d) x + 5 . 2 - ( 32 + 16 . 3 : 6 - 15 ) = 0
1) Tìm x biết:
a)-(2x-16)-(x-8)=24
b)-3.(-x-4)-x=42-24
c)|2x-4|-16=-8
2-(5 và 3/8 + x - 7 và 5/24) :16 và 2/3=0 tìm x
Tim x
1) 1/4 + 1/3 : 3x = -5
2) 1- ( 5/3/8 + x - 7/5/24 ) : ( -16/2/3 ) = 0
3) ( 1/1/3 - 25% - 5/12 ) + 2x = 1,6 : 3/5
