Answer:
<u><em>Christopher is 24 years old.</em></u>
Step-by-step explanation:
<u>c = Christopher's age</u>
<u>i = Ishaan</u>
c = i - 20
(i- 14) = 3(c - 14)
<em>simplify</em>
i - 14 = 3c - 42
i - 14 = 3(i - 20) - 42
i - 14 = 3i - 60 - 42
i - 14 = 3i - 102
<em>take i to the other side</em>
- 14 = 2i - 102
<em>take - 102 to the other side</em>
88 = 2i
44 = i
<u>Ishaan is 44 years old.</u>
<em>The question said to find Christopher's age. So:</em>
c = i - 20
c = 44 - 20
c = 24
<u><em>Christopher is 24 years old.</em></u>
