help me, please!!!
Bài 1. Tìm x, biết:
a/ 1/4.(x-3)+2=1/5
b/ 1/7-2.(x+1)=1/4+2/3
c/ 1/4.(2x+3)-1/9=2/5
d/ 3/2.(x+1)-4/9=2/3
e/ 4/5.(2-3x)+4/7=2và1/3
[Cần gấp ạ!]
Tìm X
2×(3/2-x)-1/3=7x-1/4
1/2×(x+2)-4×(x-1/4)=1/2x

B1:tìm x biết a, (-2+x^2)(x^2-2)(x^2-2)(x^2-2)(x^2-2)=1 b, (2x+3)(x-4)+(x-5)(x-2)=(3x-5)(x-4) c,(8x-3)(3x+2)-(4x+7)(x+4)=(4x+1)(5x-1) d, 2x^2+3(x-1)(x+1)=5x(x+1) e, (8-5x)(x+2)+4(x-2)(x+1)=(2+x)(2-x) f, 4(x-1)(x+5)-(x+2)(x+5)=3(x-1)(x+2)
TÌM X, BIẾT:
a) 3 . ( 1/2 - x ) + 1/3 = 7/6 - x
b) 4 . ( 1/2 - x ) - 5 . ( x - 3/10 ) = 7/4
c) -3/2 . ( 4/5 - 2/3 ) + x = 4 . ( x - 1/2 )
d) 2 . ( 3/2 - x ) - 1/3 = 7x - 1/4
e) 1/5 . ( -3/5 -10 ) + 5x = x - 2/3
f) -3/2 . ( 5 - 1/6 ) + 4 . ( x - 1/2 ) = 1
