In page 43, math problem 1, on Math 4 Workbook, Part One, Vietnamese Education Publishing House:
The sum of mother and son's ages is 42. The mother is 30 years older than her son. How old is the mother and her son?

Try something like:

sage: var('x,y');
sage: solve([x + y == 42, x - y == 30], [x, y])
[[x == 36, y == 6]]

(Or just ignore sage code, and use plain thoughts or simple drawings.)
