Graphically
As we can see in the graph, the lines intersect in the ordered pair (-2,7). Then, the solution to the system comprised of these two lines is:
[tex]\begin{cases}x=-2 \\ y=7\end{cases}[/tex]
Mathematically
To solve the given system of equations, we can use the equalization method.
Step 1: Either variable is chosen and solved in both equations.
[tex]\begin{cases}y=0.5x+8\Rightarrow\text{ Equation 1} \\ y=5-x\Rightarrow\text{ Equation 2}\end{cases}[/tex]
Step 2: The expressions are equalized, obtaining an equation with a variable.
[tex]0.5x+8=5-x[/tex]
Step 3: We solve for x the resulting equation:
[tex]undefined[/tex]
