Tim’s age in 7 years will be three times what it was 19 years ago.

Let x be Tim's age.

x + 7 = 3(x - 19)

For solution:

x + 7 = 3(x - 19)

x + 7 = 3x - 57

7 + 57 = 3x - x

64 = 2x

64/2 = x

32 = x

Let's check:

(32) + 7 = 3([32] - 19)

39 = 3(13)

39 = 39

Let x be Tim's age.

x + 7 = 3(x - 19)

For solution:

x + 7 = 3(x - 19)

x + 7 = 3x - 57

7 + 57 = 3x - x

64 = 2x

64/2 = x

32 = x

Let's check:

(32) + 7 = 3([32] - 19)

39 = 3(13)

39 = 39
