Answer: [tex]k= d+3[/tex]
[tex]k-2 = 4(d-2)[/tex]
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. Age of Kelvin = Age of Daniel+ 3
i.e. In terms of variables , k= d+3 (1)
Two years ago,
Age of Kelvin = k-2
Age of Daniel = d-2
Since Two years ago ,Kevin was 4 times as old as Daniel.
i.e. In terms of variables : [tex]k-2 = 4\times(d-2)[/tex]
[tex]k-2 = 4(d-2)[/tex] (2)
From (1) and (2) the system of equations represents this situation are
[tex]k= d+3[/tex]
[tex]k-2 = 4(d-2)[/tex]
