Let us assume Gary's age = g years.

Tom is four less than twice of Gary's age.

We took g for Gary's age, therefore "4 less than twice of g would be" 2g-4.

Therefore, Tom's age = 2g-4.

Rebecca is two less than half Gary's age after it was increased by three.

After increasing g by 3, we get g+3.

Half of (g+3) = 1/2 (g+3).

Now 2 less than half after it was increased by three = 1/2 (g+3) - 2.

Therefore, Rebecca's age = 1/2 (g+3) - 2.

Sam's age = 7 more than Gary's age : 78 less than Gary's age.

Therefore, Sam's age = (g+7) / (g-8).
