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.

Total bill = $99

Let 'n' be the number of people who ordered the chicken dinner.

Let '6-n' be the number of people who ordered the steak dinner.

Thus, the equation becomes

$14n + 17(6-n) = 99$

$14n + 102 - 17n = 99$

$-3n = 99 - 102$

$-3n = -3$

Divide both sides by -3

$n = 1$

and

$6-n = 6-1 = 5$

Therefore, we conclude that:

The number of people who ordered the chicken dinner = 1

The number of people who ordered the steak dinner = 5
