Tim x ,y biet :
2x+1 /5 =3y-2 /7 =2x +3y-1/6x
làm giùm đi mình đang cần gấp lắm
nhanh dung tich lien
tim x biet :
a) ( 2x^2+4 ) - (x^2-3/2 ) = (-3+4x^2)+ ( -4x^2/3+1)
b) ( I xI -4) - ( 2- I-xI ) = 1/3 . I xI -5
tim x biet :
a) ( 2x2+4 ) - (x2-3/2 ) = (-3+4x2)+ ( -4x2/3+1)
b) ( I xI -4) - ( 2- I-xI ) = 1/3 . I xI -5

tìm x biết :
a, I 5x -4 I = I x+2 I
b, I x + \(\frac{2}{5}\) I = 2x
c, I x -1 I + I x - 3 I = 2x - 1
d, I 5x +1 I + I 6y -8 I < hoặc bằng 0

Tim x biet |2x-1|+|1-2x|=8
tim x :
