Let's see. Looks like easy substitution here.

X - 2Y = 6

3X - 6Y = 18

express one variable in term of another with top equation

X - 2Y = 6

X = 2Y + 6

insert into bottom equation

3(2Y + 6) - 6Y = 18

6Y + 18 - 6Y = 18

---------------------------------admits of no solution here, try elimination

- 3(X - 2Y = 6)

3X - 6Y = 18

- 3X + 6Y = - 18

3X - 6Y = 18

This system either admits of no solution, or an infinite number of solutions, but my systems work is rusty, so I do not remember the terms
