Problem:

Gary, Barry and Terry belong to a car club. Gary’s car is, five times as old as Barry’s car, and Terry’s car is, six years younger than Gary’s. In three years, the age of Terry’s car will be twice the age of Barry’s. How old is Gary’s car now?

Code:

```
GARY BARRY TERRY
Now: 5x x 5x – 6
Later: 5x + 3 x + 3 2(x + 3)
```

x + 3 = 2x + 6

subtract -3 from both sides

1x = 2x + 3

subtract -2x from both sides

-1x = 3

Divide both sides by -1

x = -3 THAT'S NOT RIGHT
