Bài 1: Joel 8 tuổi. Mẹ của cậu 34 tuổi. Hỏi trong bao nhiêu năm nữa, tuổi của của mẹ cậu gấp ba lần tuổi của Joel?
Giải:
Gọi số năm là x => tuổi của mẹ trong x năm là 34 + x; tuổi của Joel trong x năm là 8 + x.
Mà trong x năm tuổi mẹ gấp 3 lần tuổi Joel
=> 34 + x = 3 * (8 + x)
<=> x = 5
Vậy đáp án là 5 năm.
