tim cac so a,b,c biet rang : a/2 = b/3 = c/4 va a + 2b -3c = -20
tim cac so a,b,c biet rang:
a/2=b/3=c/4 va a+ 2b - 3c = -20
tim cac so thuc a,b,c biet 3a-2b/4=2c-4a/3=4b-3c/2 va |a|-|b|-|c|=-10
tim a,b,c biet a=2b=3/2c va a^2+b^3-5c=a+b^3-5/3c
tim a,b ,c biet a/2=2b/3=3c/4 biet a-b15
tinh a,b,c biet a-1/2=b-2/3=c-3/4 va a -2b+3c=-14
tim a,b,c biet 2a=5b=3c va a+b-c=-44
Tim cac so a,b,c biet rang. A/2=b/3,b/5=c/4 va a2-3c=-20
tim ti so a/d biet rang : a-b/d-c=3/8 va 8b=3c
