The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.
Knowing that the dimensions of the wall are by
, its area is:
As they are planning that the dimensions of the mural be by
, its area is:
Then the area of the remaining wall after the mural has been painted is:
The solution to the given system of linear equations is (3, -1)
<h3>Graph of Linear Equations</h3>From the question, we are to determine the graph of the system of linear equations
The given system of equations is
x - 2y = 5
3x + 15y = -6
The graph of the given system of equation is shown below
From the graph,
The point of intersection of the lines is at (3, -1)
Hence, the solution to the given system of linear equations is (3, -1)
