Q. Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.\newlineYesterday a chef used 5151 eggs to make 99 chocolate souffles and 88 lemon meringue pies. The day before, he made 11 chocolate souffle and 88 lemon meringue pies, which used 2727 eggs. How many eggs does each dessert require?\newlineA chocolate souffle requires _\_ eggs and a lemon meringue pie requires _\_ eggs.
  1. Define Variables: Let's define variables for the number of eggs required for each dessert. Let xx be the number of eggs required for a chocolate souffle and yy be the number of eggs required for a lemon meringue pie.
  2. First Equation: According to the problem, 99 chocolate souffles and 88 lemon meringue pies used 5151 eggs. This gives us the first equation:\newline9x+8y=519x + 8y = 51
  3. Second Equation: The problem also states that 11 chocolate souffle and 88 lemon meringue pies used 2727 eggs. This gives us the second equation:\newlinex+8y=27x + 8y = 27
  4. Elimination Method: We now have a system of two equations:\newline9x+8y=519x + 8y = 51\newlinex+8y=27x + 8y = 27\newlineWe can solve this system using the substitution or elimination method. Let's use the elimination method by subtracting the second equation from the first to eliminate yy.\newline(9x+8y)(x+8y)=5127(9x + 8y) - (x + 8y) = 51 - 27
  5. Solve for x: Perform the subtraction to solve for x:\newline9xx+8y8y=51279x - x + 8y - 8y = 51 - 27\newline8x=248x = 24\newlinex=248x = \frac{24}{8}\newlinex=3x = 3\newlineSo, a chocolate souffle requires 33 eggs.
  6. Substitute for y: 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:\newline3+8y=273 + 8y = 27
  7. Solve for y: Subtract 33 from both sides to solve for y:\newline8y=2738y = 27 - 3\newline8y=248y = 24\newliney=24/8y = 24 / 8\newliney=3y = 3\newlineSo, a lemon meringue pie also requires 33 eggs.
