Step-by-step explanation:
Say you are X years old, your brother is Y years old, are your sister is Z years old.
Your brother is 5 years older than you can be shown as the equation:
Y = X + 5
or
X = Y - 5
Your sister is 3 years younger than you can be shown as:
Z = X - 3
or
X = Z + 3
(a) When your brother was 10, X = 10 - 5, so you were 5.
(b) When your brother is 29, X = 29 - 5, so you were 24. When you were 24, Z = 24 - 3, your sister was 21.
(c) When you were n, you can just use the equation above, but switch the variables: Z = N - 3.
(d) When your brother was K: X = K - 5
(e) Y = X + 5 and X = Z + 3
Y = (Z + 3) + 5
Y = Z + 8
So your brother is 8 years older than your sister.

Step-by-step explanation:
-1.12
=-(100/100)-(12/100)
