We have the following:

[tex]\begin{gathered} y=-\frac{1}{2}x+4 \\ y=2x-1 \end{gathered}[/tex]

Solving by substitution

[tex]\begin{gathered} -\frac{1}{2}x+4=2x-1 \\ 2x+\frac{1}{2}x=4+1 \\ \frac{5}{2}x=5 \\ x=\frac{2\cdot5}{5} \\ x=2 \end{gathered}[/tex]

Now for y

[tex]\begin{gathered} y=2\cdot2-1=4-1=3 \\ \end{gathered}[/tex]

Therefore, the answer is:

[tex](2,3)[/tex]
