Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.\newlineTwo classmates got together over the weekend to do their assigned History reading. Kathleen can read 22 pages per minute, while Tanvi can read 44 pages per minute. When they met, Kathleen had already read 8383 pages, and Tanvi had already gotten through 4747 pages. After a while, they had both read the same number of pages. How many pages had each one read? How long did that take?\newlineKathleen and Tanvi had each read _\_ pages after _\_ minutes.
  1. Define Variables: Let's define the variables.\newlineLet xx be the number of minutes they read together.\newlineLet yy be the total number of pages each had read after xx minutes.\newlineKathleen's reading speed is 22 pages per minute, and she had already read 8383 pages.\newlineTanvi's reading speed is 44 pages per minute, and she had already read 4747 pages.
  2. Write Equations: Write the equations based on the given information.\newlineFor Kathleen: y=2x+83y = 2x + 83\newlineFor Tanvi: y=4x+47y = 4x + 47
  3. Substitution to Solve: Use substitution to solve for xx. Since both equations equal yy, we can set them equal to each other: 2x+83=4x+472x + 83 = 4x + 47
  4. Solve for x: Solve the equation for x.\newline2x+83=4x+472x + 83 = 4x + 47\newline8347=4x2x83 - 47 = 4x - 2x\newline36=2x36 = 2x\newlinex=362x = \frac{36}{2}\newlinex=18x = 18
  5. Find Total Pages: Use the value of xx to find yy, the total number of pages read.\newlineWe can use either equation, but let's use Kathleen's equation:\newliney=2x+83y = 2x + 83\newliney=2(18)+83y = 2(18) + 83\newliney=36+83y = 36 + 83\newline$y = \(119\)
