Hey. For a common test tomorrow I need to know how to work out (algerbraicly) how to do these type of problem solving questions.

If anyone could help it would be much appreciated.

Silvio is 10 years older than Bonita. The sum of their ages is 4 times Bonita's age. What is their ages?

From what I can understand:

Silvio: Silvio = Bonita + 10

Bonitia: Bonita = Bonita

Sum: 4 x Bonita

Thanks,

Adrian
