You make up a table of ordered pairs for each equation.
I'd re-write them as
y = 1 - (1/3)x and
y = -1 -(1/3)x
Then make up a table of x and y for each of them and graph them out.

Divide the first equation by 2

x + 3y = 3

Divide the second equation by 3

x + 3y = -9

So, as you can see, both of them have the same left side equals to each other and the right side is different. This is because these straight lines are parallell

8x+9y=120 this is equation 1.2x+6y=12 this is equation 2... 1 and 2 to get 11y.y=-1 plug y into equation 2 to get 3x-2(-1)...
