(10-2x)+ 2/3= 8/3
5x= 8/3-2/3
5x= 6/3
5x= 2 (rút gọn)
x= 2/5
x= 0,4
(10-2x)+2/3=8/3
=>10-2x=8/3-2/3
=>10-2x=2
=>2x=8
=>x=4
a,-2\3x+1\5=1\10
b,2|1\2x-3\8|-3\2=1\4
c,-5(x+1\5)-1\2(x-2\3)=3\2x-5\6

g,4\5-1\2x=1\10
Tìm x:
a) 2/3 + 1/3 : x= 3/5
b) ( 2x/3 - 3 ) : (-10) = 2/5
c) | 2x + 1 | = 4
d) | 2x - 1 | +1 = 4
e ) 8 - | 1 - 3x | = 1/81
f) 1,5 x - 7/3 * x = 1,5 - 2/3
g) (1/2)^2x-1 = 1/8
h) ( -1/3 )^x-3 = 1/81
tifm x
4.(x-2)+10=5-3x
4x-8-10=7-x
14.(x-6)=-7.(3+2)=13.x
35.(4-3)-3.x=8-4.x
|2x-1|=3
|1-2x|=5
|4+x|=10
giải gìm mk nha mk sắp kiểm tra rùi
tìm số nguyên x biết
a) -x/2+ 2x/3 + x+1/4 + 2x+1/6 = 3/8
b) 3/2x+1 + 10/4x+2 - 6/6x+3 = 12/26
Tìm số tự nhiên x biết:
a) (10-2x).(3x-18)=0 b) 10 + 2x = 165: 216 c) 28 - 2.(x - 4)2=10 d) (15-x)3.(x2 + 16) = 0 e) 52x - 3 - 2.52 = 52 . 3
f) (8 - x3).(x2 + 16) = 0 j) (2x + 5) + (2x + 10) +(2x + 15) +...+(2x + 95) = 77520
a,3x2-5.32=2x2-9
b,(10-2x)3+8=42
c,32x+1+73=(2.5)2
d,23.(x+2)2-102=100
a,2/5+3/7+-3/5
b,1-5/7:x=-1/3
c,4/5*(x-1/3)=15/8
d,2/3:(2x+1/8)=7/3
e,2x+3/4=10/3-5/4
giúp mình với
a,( 2x-2)^3=8
b,7^x+2=49^5:7^9
c,(5x-2)^2=10^3:10^4
