Ruby o mogolo go feta Sam ga 6. Mo dingwageng di le 9, Ruby o tla bo a godile go feta Sam ga 3. Sam o na le dingwaga di le kae gone jaanong?

Mico and Marco wanted to get to know each other. They realized that the sum of their ages is 20. What will be the sum of their ages in 10 years?
A re re dingwaga tsa ga Sam ke x mme dingwaga tsa ga Ruby ke Y. Dingwaga tsa ga Ruby gone jaanong ke 6 ga tsa ga Sam, ka jalo 6 * x = Y dingwaga.
Mo dingwageng di le 9 dingwaga tsa ga Ruby e tla bo e le 3 ga tsa ga Sam, ka jalo, 3 * (x + 9) = (Y + 9) dingwaga.
Go bona dingwaga tsa ga Sam, re tsenya kgato ya ntlha mo go ya bobedi go bona 3 * (x + 9) = (6 * x) + 9.
Re arola ka lehlakore le lengwe la equation go bona (3 * x) + 27 = (6 * x) + 9.
Re tlhaola dingwaga tsa ga Sam ka lehlakore le lengwe la equation go bona 27 - 9 = (6 * x) - (3 * x).
Re tlhofofatsa equation go bona 18 = 3 * x.
Jaanong re a itse gore dingwaga tsa ga Sam ke 18 / 3 = <<18/3=6>>6 dingwaga.

There will be an additional 10 (for Mico) + 10 9for Marco) = <<10+10=20>>20 to Mico and Marco's current sum of ages in 10 years.
Therefore, the sum of their ages in 10 years is 20 + 20 = <<20+20=40>>40.
