Your family goes to a restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for $14.80, and some order steak for $17. If the total bill was $91, which system could you use to find out how many chicken dinners and how many steaks dinners were ordered?​

5 order chicken 1 orders steak

x = number who order chicken

y = number who order steak

x+y=6

14.8x + 17y =91

14.8x + 17*(6-x) = 91

-2.2x +102 = 91

-2.2x = -11

x = 5

y = 6-x = 1
