1 answer:
Answer:
dean = 10
franco = 50
helen = 2
steps
you want to get the age of one of the people first
'is' means equal
'older than' means plus
'sum' means total by adding
d
f = 5d
d = 8 + h
d + f + h = 62
make sure there is 1 letter to solve for
d = 8 + h -> h = d - 8
f = 5d
d = d
d + f + h = 62
d + (5d) + (d-8)
7d - 8 = 62
7d = 70
d = 10
f = 50
h = 2
