cho x,y thoa man :x-2/2=y-3/3 va x+y=10 khi do xy=
cho x,y thoa man x/3 = y/5 va x+y=16 khi do x^2+y^2=........
cho x,y,z thoa man x/2=2y/3=3z/4 va x-y=15. khi do x-y-z la
cho 3 so x;y;z thoa man 3x =2y ; 7y=5z va x+z-y =32 . khi do x+y-z= ?
cho hai so tu nhien x va y thoa man 2^x+1*3^y=12^x khi do x+y=
ai giup dau tien cho 2 like
Cho hai so tu nhien x va y thoa man 2x+1.3y=12x
khi do x+y= ?
Biet x;y;z thoa man x-1/2=y-2/3=x-3/4 va x-2y+3x=-10. Khi do x+y+z =?
cho cac so x,y,z thoa man( x-1)/2=(y-2)/3=(z-3)/4 va 2x +3y-z=95 khi do x+y+z =
ai nhanh minh tich
biet x;y;z thoa man: (x-1)/2 = (y-2)/3 = (z-3)/4 va x-2y+3z = -10
khi do x+y+z = ?
