Respuesta :
The solution of system of equations are [tex](4,0)[/tex]
Therefore, Trevor conclusion is true.
System of equations:
Given system of equations;
         [tex]x- 2y = 4\\\\y=4-x[/tex]
Substitute value of y from equation (2) in equation (1).
      [tex]x-2(4-x)=4\\\\x-8+2x=4\\\\3x=12\\\\\\x=12/3=4[/tex]
Substitute value of x in second equation.
 [tex]y=4-x=4-4=0[/tex]
Hence, the solution of system of equations are [tex](4,0)[/tex]
