Answer: B.  k=d+3

              k-2=4(d-2)

Step-by-step explanation:

Let k be Kevin’s age and let d be Daniel’s age.

Given : Kevin is 3 years older than Daniel.

i.e. k=d+3

Kevin's age two years ago= k-2

Two years ago, Kevin was 4 times as old as Daniel.

i.e. k-2=4(d-2)

Hence, the system of equations represents this situation :

k=d+3

k-2=4(d-2)
