tim x biet: a) |x+2| - 6x=7 b) |x-3|+|x+2|=7
BAI 1 : Tim x;y;z biet 6x 3/5 4y 6x/7 3z 4y Va 2x 3y 5z 21
tim x , y biet :
2x+1/5=3y-1/7=2x+3y-1/6x
choP(x) =ax^ 4-6x^ 3 +7 -2x^ 2-4x^ 4 tim a biet p(x) co bac la 3
toan 7 tim x,y,z biet (xy/2y+4x)=(yz/4z+6y)=(zx/6x+2z)=(x^2+y^2+z^2)/2^2+4^2+6^2
Bai tap ve day ti so bang nhau
BAI 1 : Tim x;y;z biet
6x-3/5 = 4y-6x/7 = 3z-4y
Va 2x+3y-5z + -21
tim x biet /x^2+/3x-1//=x^2+7
tim x biet :
-x-2/3=-6/7
4/7-x=1/3
Tim x ,y biet :
2x+1 /5 =3y-2 /7 =2x +3y-1/6x
làm giùm đi mình đang cần gấp lắm
