Question

Mel is 3 years older than rahfat and aurelio is twice as old as mel. the sum of their age is 57. how old is mel?

Answer 1

M=15 years old I think

Answer 2

m = r + 3
a = 2m......a = 2(r + 3).....a = 2r + 6
m + r + a = 57

(r + 3) + r + (2r + 6) = 57
4r + 9 = 57
4r = 57 - 9
4r = 48
r = 48/4
r = 12.......rahfat is 12

a = 2r + 6
a = 2(12) + 6
a = 24 + 6
a = 30.......aurello is 30

m = r + 3
m = 12 + 3
m = 15 <=== mel is 15
