Gọi số tuổi của 3 người lần lượt là a,b,c
Ta có: a=2b=c+10
=> b=1/2 a; c=a-10
Do đó : a+b+c=30
hay a+1/2a+a-10=30
=> a+1/2a+a=40
5/2a=40
Nên a= 16
Từ đó ta suy ra b=8 ;c=6
Vậy số tuổi của ba bạn lần lượt là 16;8 và 6
Chúc bạn làm bài tốt :)

Call three chirle is a,b,c
I have: a= 2b = c+10
=> b =\(\frac{1}{2}\) a+a=10+30
=>a+\(\frac{1}{2}a+a-10=30\)
\(=>\frac{5}{2}a=40\)
*that you have to:a=16
And three chirlen are: b= 8 c=6
a=16
