Answer:
Infinitely many solutions.
Step-by-step explanation:
Systems of equations can be solved through substitution, elimination, or graphing. For this problem, let's solve the system through substitution.
Given the system of equations:
Focusing on the first given equation, we can solve for the x-variable by adding the term "2y" to both sides of the equation:
Now that we have a value for the x-variable, we can substitute that value into the second equation for x:
Following PEMDAS, distribute "3" to each term within the parentheses:
Now, let's combine like terms:
Our result indicates there are an infinite number of solutions to this system of equations as "24=24" is a statement that will always be true.
In the attached image, you can see that these equations have the same graph, which is additional support for the fact this system of equations has an infinite number of solutions that are true.
Answer:
Step-by-step explanation:
You have the following information given in the problem:
- The number of soccer fans that are going to a soccer game is 27.
- A ticket to the game costs $18 per person.
- The cost of the lunch for all 27 fans is $172.
- represents the total cost of attending the game for all 27 fans.
Therefore, keeping the above on mind you can write the following expression that closely estimates the total cost of attending the game for all 27 fans:
