Answer 2

Answer:

The answer to your question is Kevin is 6 years old.

Step-by-step explanation:

Process

1.- Assign a letter to Daniel and another letter to Kevin

Daniel = d

Kevin = k

2.- Write equation that help to solve this problem

      k = d + 3         equation l

       k = 4d             equation ll          four years ago

3.- Solve the system by substitution. Substitute equation ll in equation l

       4d = d + 3

-Solve for d

       4d - d = 3

       3d = 3

         d = 1

-Find k

       k = 1 + 3

       k = 4

4.- Calculate the age Kevin has now

Kevin's age = 4 + 2

                   = 6
