3x+3y/y+x>6
3x+3y+3x+3y/x+y+z+x
3y/2+37/y>18
Bai 1;Tim x,y,z
a; x/z+y+1=y/x+z+1=z/x+y-2=x+y+z
b; 3x/8=3y/64=3z/216 va 2x^2+2y^2-z^2=1
Tim x,y,z:\(\frac{x-1}{2}=\frac{y-2}{3}=\frac{z-3}{4}\) và 2x+3y-z=95
2x=3y va x.y =-7 tim x va y
x/2=y/3=z/5 va x.y .z=-240
ai lam minh tick tim x va y va z nha
tim x,y € z
xy-x+2y=3
2x^2+3y^2=77
Tim x,y,z biet:
a) x/3 = y/-4 = z/-5 va 2x + 3y - 4z = 70
b) x/3 = y/2; x/5 = 2/7 va x+y+z = 184
c) x/5 = y/-7 ; y/4 = z/15 va x+3y-4z=18
d) 2x/3 = 3y/4 = 4z/5 va x+y+z=49
e) x/y = 3/7 va x.y = 84
Help me, pleass!!
Hoi dong ARMY dung vo tam luot qua nhe!!
Ai nhanh nhat to tick cho!!😘
