Ответ:
(20,5) is NOT a solution of the equation
.
The point (20,5) implies that there are 20 small tables and 5 large tables.
Step-by-step explanation:
We have been given that a catering company is expecting 150 people to attend the wedding. There are two types of tables, ones which can fit 6 people and ones which can fit 10 people.
If there are x tables which can fit 6 people and there are y tables which can fit 10 people, we can express the total number of people that can fit on all available tables as:
.
Since there are total 150 people expected in the wedding, the equation can be framed as:
.
Let us check if the point (20,5) is a solution of the equation.
Since we get a false statement, therefore, (20,5) is NOT a solution of the equation
.
The point (20,5) implies that there are 20 small tables and 5 large tables.
