The fifth grade mathematics volume two questions; Xiaojun and his mother are both 36 years old now. Three years later, his mother was 26 years older than Xiaojun. How old are Xiaojun and his mother this year? This is easy to calculate. Three years later, their total age is 42. Knowing that their mother is 26 years older than Xiaojun, we can find Xiaojun's age after three years: (36+3x2-26) divided by 2, Xiaojun's age after three years is 8 years, and Xiaojun's age before three years is 8-3=5 years. So we can find that her present age is 36-5=3 1 year.
