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(2-3y) + 5y = 8

4 - 6y + 5y = 8

-y = 4

y = -4

then x = 2 -3(-4) =14

x= 14 , y = -4
