Hi! This is my first time helping someone so I hope this helps!
X=1
Y=5
First in the first equation, subtract x on both sides.
Y= 6-x
Then substitute that into the second equation.
-3x + 6-x = 2
-4x + 6= 2
-4x = -4
x= 1
Substitute it to the first equation
Y= 6-1
Y= 5
X= 1
Hope this helps. I hope you have a great day!
