45 + 3x and 108 - 4x

45 + 3x = 108 - 4x

3x = 108 - 45 - 4x

3x = 63 - 4x

9x = 63

x = 63/9

x = 7

Scott is four more than double the age of Todd. Scott is 56. What is Todd's age?
SSSSS [86.1K]

Answer: 26 years old

Step-by-step explanation:

Since Scott is four more than double the age of Todd, start by taking away four from Scott's age.

56-4=52

Then take half of that because that would be double of Todd's age

52/2=26

Todd is 26 years old.
