Tìm x
a) 1/3x + 2/5( x - 1 ) = 0
b) (2x - 3 )(6 - 2x ) =0
c) 2|1/2x - 1/3 | - 3/2 = 1/4
d) 3/4 - 2 . | 2x - 2/3 | = 2
e) ( 3x - 1)(-1/2x + 5 ) = 0
g)-5(x + 1/5 ) - 1/2(x - 2/3 ) = 2/3x - 5/6
h) 3(x - 1/2 ) - 5(x + 3/5 ) = -3 + 1/5
i) 60%x + 2/3x = 1/3. 6và1/3 ( 6và1/3 là hỗn số )
Tìm giá trị tuyệt đối :
a) |2x - 5| = 4 b) 1/3 - |5/4 - 2x| = 1/4 c) 1/2 - |x + 1/5| = 1/3 d) 3/4 - |2x + 1| = 7/8

giúp mình với

2) 5 ( x + 1 ) + 3 ( 2x + 1 ) = 65
3 ) 3 ( 4 + 3x ) + 5 ( 1 + 2x ) = 100
a. 3(x-1/2) - 5(x+3/5=-x+1/5
b. 2/3× + 1/2x = 5/2:15/4
c. 3x + 2x = 5/8 × 4/3
d. 17/2 - |2x - 3/4| = -7/4
e. (x + 1/25) + 17/25 = 26/25
f. 2/3x - 1/2x = 5/12
