Mohammed · Answer 1

Our system is : S + L = 19, and 3S + 6L = 87

Let # of small rooms = S

# of Large rooms = L

10 Large rooms and 9 Small rooms

Step-by-step explanation:

Let # of small rooms = S

# of Large rooms = L

S + L = 19

3*S + 6*L = 87

Our system is : S + L = 19, and 3S + 6L = 87

solve.

S = 19 - L

3 * (19 - L) + 6L = 87

57 - 3L + 6L = 87

57 + 3L = 87

3L = 30

L = 10

S = 19 - 10 = 9

Keyla Rowland · Answer 2

Step-by-step explanation:

Let the number of smaller rooms be x

Total rooms are 19. So, number of larger rooms = 19 - x

Total guests = 87

3x + (19-x) 6 = 87
