Answer:

[tex]\huge \boxed{x=-3 \ \mathrm{and} \ y=17}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

Subtracting both equations:

    5x + y = 2

 -  (4x + y = 5)

————————

1x + 0y = -3

x = -3

Substituting x = -3 for the second equation:

4(-3) + y = 5

Solving for y.

-12 + y = 5

y = 17
