Okay. So I am completely lost with this... Any help would be great!
3. Solve the system using any method – graphing, substitution, or linear combination. Make sure to show your work.
2x + 5y= 8
x + 3y= 2

Whenever you have a variable showing up as an x or y with coefficient of 1 understood, I use substitution
from the 2nd , x = 2  3y, now plug into the 1st
2(23y) + 5y = 8
4  6y + 5y = 8
y = 4
y = 4
then x = 2 3(4) =14
x= 14 , y = 4
