Answer:
We conclude that:
- The number of people who ordered the chicken dinner = 1
- The number of people who ordered the steak dinner = 5
Step-by-step explanation:
Given that 
- Some order the chicken dinner for $14
- some order the steak dinner for $17.
- Let 'n' be the number of people who ordered the chicken dinner.

Thus, the equation becomes




Divide both sides by -3

and 

Therefore, we conclude that:
- The number of people who ordered the chicken dinner = 1
- The number of people who ordered the steak dinner = 5
