Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.\newlineA baseball coach takes her team out for pizza every time they win a game. Not everyone can come each time, so she orders the pizzas based on how many players are coming. After last week's victory, she bought 33 small pizzas and 22 large pizzas, the perfect amount for the 1414 players going out for pizza. This week, there were 1212 players going, so she ordered 22 small pizzas and 22 large pizzas, which was also the right amount. How many people does each size of pizza feed?\newlineEach small pizza feeds _\_ people, and each large pizza feeds _\_ people.

Q. Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.\newlineA baseball coach takes her team out for pizza every time they win a game. Not everyone can come each time, so she orders the pizzas based on how many players are coming. After last week's victory, she bought 33 small pizzas and 22 large pizzas, the perfect amount for the 1414 players going out for pizza. This week, there were 1212 players going, so she ordered 22 small pizzas and 22 large pizzas, which was also the right amount. How many people does each size of pizza feed?\newlineEach small pizza feeds _\_ people, and each large pizza feeds _\_ people.
  1. Define Variables: Let's denote the number of people a small pizza can feed as xx and the number of people a large pizza can feed as yy. After last week's victory, the coach bought 33 small pizzas and 22 large pizzas for 1414 players. This gives us our first equation:\newline3x+2y=143x + 2y = 14
  2. First Equation: This week, there were 1212 players going, and the coach ordered 22 small pizzas and 22 large pizzas. This gives us our second equation:\newline2x+2y=122x + 2y = 12
  3. Second Equation: We now have a system of equations:\newline3x+2y=143x + 2y = 14\newline2x+2y=122x + 2y = 12\newlineWe can solve this system by subtracting the second equation from the first to eliminate yy.\newline(3x+2y)(2x+2y)=1412(3x + 2y) - (2x + 2y) = 14 - 12\newline3x2x+2y2y=23x - 2x + 2y - 2y = 2\newlinex=2x = 2
  4. Solve System of Equations: Now that we have the value for xx, we can substitute it back into one of the original equations to solve for yy. Let's use the second equation:\newline2(2)+2y=122(2) + 2y = 12\newline4+2y=124 + 2y = 12\newline2y=1242y = 12 - 4\newline2y=82y = 8\newliney=4y = 4
  5. Substitute and Solve for xx: We have found the values for xx and yy:x=2x = 2y=4y = 4This means each small pizza feeds 22 people, and each large pizza feeds 44 people.
