I have forgotten the formula for sovling this type of question. Or is just my age?

Maurice and Mike total age 88

Cynthia and Mike total age 76

Cynthia and Maurice total age 80

what is the age of each individual?

Many thanks if you can help. My mind has just gone blank!!

Doing it the long way round.......
ma+mi=88
mi=76-c
ma=80-c
Eliminate c and you should get there :o)
1 Mc + Mi = 88
2 Mi + C = 76
3 Mc + C = 80

1 - 2 , Mi - C =8

Mi + C + Mi -C = 76+8 =84
2Mi =84
Mi = 42
substitute back, C = 42-8, Mc= 88-42
