john has 2 cousins. Their ages total to 19. One cousin is 4 years more than twice the age of the other cousin. Find the age of both cousins.
Let x = age of one cousin
Let y = age of the other cousin
x + y = 19
x = 2y + 4
2y + 4 + y = 19
3y = 15
y = 5
x = 19 - 5 = 14
the older cousin is 14 years old
the younger cousin is 5 years old
