My name is Ann [436]

Answer:

x = 5

y = 4

Step-by-step explanation:

multiply the second equation by -1 and add the first equation to eliminate "x"

$4x+6y=44\\-4x-2y=-28$
_____________

$4y=16$

$y=16/4 =4$

Replace "y" in the first equation:

$4x+6(4)=44$

$4x+24=44$

$4x=44-24$

$x=20/4=5$

Hope this helps
