BAI 1 : Tim x;y;z biet 6x 3/5 4y 6x/7 3z 4y Va 2x 3y 5z 21
a, Tim x biet:/x-2/+/3-2x/=2x+1
b, Tim x,y thuoc Z biet:xy+2x-y=5
c, tim x,y,z, biet :2x=3y;4y=5zva 4x-3y+5z=7
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,y sao cho:
a,-22/15x+1/3=lx+15l
b,2x+1/5=3y-2/7=2x+3y-1/6x
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
tìm x,y biết 2x+1/5=3y-2/7=2x+3y-1/6x
Tìm x,y biết: (2x+1)/5 = (3y-2)/7 = (2x+3y-1)/(6x)
cho x, y thỏa mãn : 2x+1/5=3y-2/7=2x+3y-1/6x. Tìm x, y
(2x+1):5=(3y-2):7=(2x+3y-1):6x tìm x;y
