Answer:
d. K−2=(d−2)+3 k=4d
Explanation:
Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. Let k be Kevin's age and let d be Daniel's age. Which system of equations represents this situation?
we have to interpret the questions and write it mathematically
Let k be Kevin's age and let d be Daniel's age.
"Kevin is 3 years older than Daniel" can be mathematically written as k= d+3
"Kevin was 4 times as old as Daniel" can be mathematically written as k = 4d
Therefore the correct option is d.
k-2 =(d-2)+ 3 k = 4d
Because k-2 = d-2+3 is the same as k= d+ 3
