The elimination method works when the equations are in what form

The answer is

Step-by-step explanation:

To find the correct equation we have to separate each one of the terms:

Typically runs = x km/hour

Sick run = 41.5 km/hour

Difference in speed = 13.5 km/hour

This is a case of a subtract, so we have to subtract the typically run and the sick run and the answer will be the difference in speed, this is=

In the terms of the answers, we have:

The answer is
