1.G=M%2F2
2.M=F-5
3.G%2BM%2BF=100
From eq. 2,
F=M%2B5
Substitute into eq. 3,
M%2F2%2BM%2BM%2B5=100
%285%2F2%29M=95
Now solve for M, then use the other equations to solve for G and F.

A girl is half the age of her mother,the mother is five years younger than the father of the girl.If the ages of the girl ,the mother and the father is added together,the answer is 100.How old is the girl? How old is the mother? And how old is the father?
Let girl's age be G
Then mother's is: 2G, and father's is: 2G + 5
We then get: G + 2G + 2G + 5 = 100
5G + 5 = 100
5G = 95
G, or girl is: highlight_green%28matrix%281%2C4%2C+95%2F5%2C+%22=%22%2C+19%2C+years-old%29%29
Mother is: highlight_green%28matrix%281%2C4%2C+2%2819%29%2C+%22=%22%2C+38%2C+years-old%29%29
Father is: highlight_green%28matrix%281%2C4%2C+38+%2B+5%2C+%22=%22%2C+43%2C+years-old%29%29
