We could use any of these numbers to start off.

We can either choose to solve for x or y it doesn't matter. I will start by solving for y in `6x + 9y =-3`

The first step is to move 6x to the other side by subtracting it because we are trying to get y alone.

`9y = -3 - 6x`

Now divide by 9 because it is standing in the way of y:

`y = -3/9 - (6x)/9`

We can simplify these:

`y = -1/3 - (2x)/3 `

Now plug in these numbers as Y on the other problem:

`-4x - 6(-1/3 - (2x)/3) = 11 `

distribute the -6

`-4x + 2 + 4x = 11 `

combine like terms:

`-4x + 4x + 2 = 11 `

2 `!=` 11

therefore there are no numbers that could satisfy this equation.
