Answer:
2x + 4y = 110
Step-by-step explanation:
Let
The quantity of small tables = x
The quantity of large tables = y
The smaller tables can fit 2 people, the larger tables can seat 4 people.
Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.
Number of people×quantity (small table) + number of people×quantity (large table) = 110
2x + 4y = 110

Answer:x=2
y=6
Step-by-step explanation:
-7*x+4*y=10
║minus
-5*x+3*y=8
----------------
-2*x+y=2
y=2+2*x
-------------
-5*x+3*(2+2*x)=8
-5*x+6+6x=8
x=8-6
x=2
-------------------------
-7*2+4*y=10
4*y=10+14
4*y=24
y=24/4
y=6
