The steps are :
[tex]x + 2y = 13 - - - (1)[/tex]
[tex] - x + y = 5 - - - (2)[/tex]
[tex](1) + (2)[/tex]
[tex]x + 2y + ( - x) + y = 13 + 5[/tex]
[tex]3y = 18[/tex]
[tex]y = 6[/tex]
[tex]substitute \: y = 6 \: into \: (2)[/tex]
[tex](2)⇒[/tex]
[tex] - x + 6 = 5[/tex]
[tex] - x = - 1[/tex]
[tex]x = 1[/tex]
Therefore, you have to insert the values into the coordinates form so the answer willl be (1 , 6).
