In a basketball game, a regular basket is worth 2 points and a long distance basket is worth 3 points. There were 54 baskets in
Alla [95]

Answer:

The system of equations for the given situation is:

x+y=54

2x+3y=118

Step-by-step explanation:

Given:

Regular basket is worth = 2 points

Long distance basket  is worth =3 points

Total baskets in a game = 54

Total points in total = 118

x\rightarrow represents the number of regular baskets

y\rightarrow represents the number of long distance baskets.

Expression for total baskets can be given by ⇒ x+y

Thus first equation representing total baskets in a game is given by:

x+y=54

Since a regular basket is worth 2 points

So x regular baskets would be worth =2x points

Since a long distance basket is worth 3 points

So y long distance baskets would be worth =3y points

Expression for total points in a game can be given by ⇒ 2x+3y

Thus second equation representing total points in a game is given by:

2x+3y=118

∴ The system of equations for the given situation is:

x+y=54

2x+3y=118
