Answer 2

Age Problem

Answer:

Kassim is $15$ years old this year.

Step-by-step explanation:

Let $k$ be Kassim's age this year.

Kassim's age after $30$ years is $k +30$. Also, $3$ times the age of Kassim is $3k$. We are told that after $30$ years, Kassim's age will be $3$ times as his age. So, $k +30 = 3k$.

Solving for $k$:

$k +30 = 3k \\ k +30 -3k = 3k -3k \\ -2k +30 = 0 \\ -2k +30 -30 = -30 \\ -2k = -30 \\ \frac{-2k}{-2} = \frac{-30}{-2} \\ k = 15$
