Answer:
[tex](5, 6)[/tex]
Step-by-step explanation:
Step 1: Solve for x in the first equation
[tex]x - y + y = -1 + y[/tex]
[tex]x = y - 1[/tex]
Step 2: Plug in x into the second equation
[tex](y - 1) - 3y = -13[/tex]
[tex]y - 1 - 3y + 1 = -13 + 1[/tex]
[tex]-2y / -2 = -12 / -2[/tex]
[tex]y = 6[/tex]
Step 3: Plug in y into the first equation
[tex]x - (6) + 6 = -1 + 6[/tex]
[tex]x = 5[/tex]
