Answer:
44yrs
Step-by-step explanation:
sum= 64
8yrs ago
Hanna = x - 8
Andrew =3x - 8
sum 8yrs ago
64 - <u>8</u> - <u>8</u> = 48 yrs
| \
Hanna's Andrew's
3x + x = 48
<u>4x</u> = <u>48</u>
4 4
x = 12
Andrew = 3x = 3 x 12 = 36( 8 yrs ago)
now = 36 + 8 = 44yrs
Hanna's = x = 12(8 yrs ago)
now = 12 + 8 = 20yrs
