Common Region of Four Equations


  • Equation 1: 5x + 3y = 30

  • Equation 2: x + y = 9

  • Equation 3: y = x/3

  • Equation 4: y = x/2



The common region shown in the diagram refers to the area where all four equations intersect. This means that any point within this region satisfies all four equations simultaneously. To find this common region, we need to solve for the intersection points of the equations.


  • Solving for Intersection of Equations 2, 3, and 4:


    • Substituting y = x/3 into x + y = 9, we get x + (x/3) = 9. Solving for x, we get x = 6.

    • Substituting x = 6 into y = x/3, we get y = 2.

    • Substituting x = 6 into y = x/2, we get y = 3.

    • Therefore, the intersection point of equations 2, 3, and 4 is (6, 2) and (6, 3).


  • Solving for Intersection of Equations 1 and 2:


    • Substituting y = 9 - x into 5x + 3y = 30, we get 5x + 3(9 - x) = 30. Solving for x, we get x = 3.

    • Substituting x = 3 into y = 9 - x, we get y = 6.

    • Therefore, the intersection point of equations 1 and 2 is (3, 6).


  • Plotting Intersection Points:


    • Plotting the intersection points of equations 2, 3, and 4 at (6, 2) and (6, 3).

    • Plotting the intersection point of equations 1 and 2 at (3, 6).


  • Shading the Common Region:


    • The common region is the shaded area where all four equations intersect. This area is bounded by the lines x = 3, x = 6, y = x/3, and y = x/2.




Therefore, the common region shown in the diagram is the area bounded by the lines x = 3, x = 6, y = x/3, and y = x/2, and it represents the set of points that satisfy all four equations simultaneously.
