Answer:
The solution is
[tex]\boxed{x=6,y=-2}[/tex]
Step-by-step explanation:
The given equations are
[tex]y=3x-20[/tex]
and
[tex]y=-2x+10[/tex]
The graph of the two equations intersects at [tex](6,-2)[/tex] as show in the graph in the attachment.
The point of intersection of the two graphs is the solution to system of equations.
Hence the solution is
[tex]x=6,y=-2[/tex]
