Answer:
(x, y) = (3, -7)
Step-by-step explanation:
[tex]\left \{ {{x - 3y = 24} \atop {5x + 3y = -6}} \right.[/tex]
[tex]\left \{ {{x-3y=24} \atop {3y=-6-5x}} \right.[/tex]
[tex]x-(-6-5x)=24[/tex]
[tex]x=3[/tex]
[tex]3y=-6-5(3)[/tex]
[tex]y=-7[/tex]
[tex](x,y)=(3,-7)[/tex]
CHECKING IF ANSWER IS CORRECT:
[tex]\left \{ {{3-3(-7)=24} \atop {5(3)+3(-7)=-6}} \right.\\\left \{ {{24=24} \atop {-6=-6}} \right. \\(x,y)=(3,-7)[/tex]
There is your answer with steps :)
