Answer 1

Answer:

$[3, 4]$

Step-by-step explanation:

{5x + 2y = 23

{13x + 3y = 51

−5⁄13[13x + 3y = 51]

{5x + 2y = 23

{−5x - 1 2⁄13y = 19 8⁄13 >> New Equation

______________________

11⁄13y = 3 5⁄13

_____ ______

11⁄13 11⁄13

$y = 4$ [Plug this back into both equations above to get the x-coordinate of 3]; $3 = x$
