Answer :
Let's solve the problem step-by-step:
1. We are given that Ed is 7 years older than Ted. So, if we let Ted's age be [tex]\( t \)[/tex], then Ed's age will be [tex]\( t + 7 \)[/tex].
2. We are also told that Ed's age is [tex]\(\frac{3}{2}\)[/tex] times Ted's age. This can be set up as the equation:
[tex]\[
t + 7 = \frac{3}{2} \times t
\][/tex]
3. To solve this equation, we can get rid of the fraction by multiplying every term by 2:
[tex]\[
2(t + 7) = 3t
\][/tex]
4. Expanding the left side gives:
[tex]\[
2t + 14 = 3t
\][/tex]
5. To isolate [tex]\( t \)[/tex], subtract [tex]\( 2t \)[/tex] from both sides:
[tex]\[
14 = 3t - 2t
\][/tex]
6. Simplifying gives:
[tex]\[
14 = t
\][/tex]
7. So, Ted is 14 years old.
8. To find Ed's age, remember Ed is 7 years older than Ted:
[tex]\[
\text{Ed's age} = 14 + 7 = 21
\][/tex]
Therefore, Ted is 14 years old, and Ed is 21 years old. The correct answer is B. Ted is 14 years old, and Ed is 21 years old.
