Answer:
x=1
Step-by-step explanation:
We distribute the negative 5 to x minus three to get 8x-5x+15=18. Then, we cancel out the 15 by subtracting it from both sides. This leaves us with 8x-5x=3. When we subtract, we get 3x=3, and when we divide both sides by 3, we get x=1. Hope this helps :)

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)
