Tìm số hữu tỉ x: -3/2 - 2x + 3/4 = -2

Bài 1: Tìm số hữu tỉ x bt rằng

a) -3/2 - 2x + 3/4 = -2
b) ( - 2/3x - 3/5)(3/-2 - 10/3) = 2/5
c) x/2 - (3x/5 - 13/5) = -( 7/5 + 7/10 . x)
d) 2x - 3/3 + -3/2 = 5 - 3x/6 - 1/3
e) 2/3x - 3/12 = 4/5 - ( 7/x -2)

f) 1/x-1 + -2/3 ( 3/4 - 6/5) = 5/2-2x
g) 3 - 2/2x-3 = 2/5+ 2/9 - 6x - 3/2
h) x/2 - 1/x = 1/12
i) x2 - 7/6x + 1/3 = 0
k) 13/x - 1 + 5/2x-2 - 6/3x - 3

m) ( 3/2 - 2/-5) : x -1/2 = 3/2

n) ( 3/2 - 5/11 - 3/13)(2x-2) = ( -3/4 +5/22 + 3/26)
