4-20.

Write an equation for the following situation. You do not need to solve it.

Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for $17$ years longer than she has owned the van. The sum of the ages of the vehicles is 41 years.

Let $x$ represent the age of the blue van.
What expression would represent the age of the red truck?

$x + 17$ is the age of the red truck.
The sum of the two ages equals $41$.
