What is the solution to the system of linear equations

There are numerous forms to find the solution to a system of linear equations:

There are three common ways:

However, you can also find the solution of the variables by graphing each equation and the point, where the two lines intersect will be the solution.

For example, if the point were the two lines intersect is (4,2) that means that:

X = 4 and Y = 2

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
