Question

#14 write the given sentence as an equation. Tim'S age in 7 years will be three times what it was 19 years ago

Answer 1

The first thing we must do for this case is to define variables.
 We have then:
 x = Tim's age
 Now we write the equation:
 x + 7 = 3 (x-19)
 Answer:
 Tim's age in 7 years will be three times what it was 19 years ago:
 x + 7 = 3 (x-19)
