Answer: [tex]x=-7, y=2[/tex]

Step-by-step explanation:

Multiplying the first equation by 2 gives [tex]2x-6y=-26[/tex]

Subtracting this from the second equation yields [tex]21y=42 \longrightarrow y=2[/tex]

Substituting this back into the first equation gives that [tex]x=-7[/tex]

[tex]\therefore x=-7, y=2[/tex]
