Apoporo di le pedi a ne a wa mo setlhareng, mme se sengwe sa wela kwa tlhogong ya ga Newton. Newton a tsaya diaporo tseo tse pedi, a tsenya se le sengwe mo kgetsing ya gagwe mme a latlhela se sengwe mo setlhareng, mme ga wa diaporo di le 5 gape. Newton a tsaya diaporo tseo, a tsenya tsotlhe mo kgetsing ya gagwe ntle le se le sengwe mme a latlhela se se setseng mo setlhareng. Gape ga wa diaporo tse 6 mo setlhareng. Newton a tsaya diaporo tsotlhe tse di setseng mme a ya le tsone kwa gae go ya go apaya kuku. Ke diaporo di le kae tse a neng a di tshotse fa a ya gae?

Wendy is five times as old as Colin will be seven years from now. In 25 years, Colin will be a third as old as Wendy is now. How old is Colin now?
Diaporo di le pedi di ne tsa wa mo setlhareng, mme Newton a latlhela se le sengwe, a sala le 2-1=<<2-1=1>>1.
Go ne ga wa diaporo tse 5 gape, mme palogotlhe ya gagwe ya nna 5+1=<<5+1=6>>6.
Newton o ne a latlhela se le sengwe mo setlhareng, a sala le 6-1=<<6-1=5>>5.
Go ne ga wa diaporo di le 6 gape, mme palogotlhe ya diaporo tsa ga Newton ya nna 5+6=<<5+6=11>>11.

Let x be Colin's age now.
(x+7)*5=(x+25)*3
5*x+35=3*x+75
2*x=40
x=<<20=20>>20
