Answer:
For x = 10:

For y = - 3:

Step-by-step Explanation:
Before we start let's recall the formula for the linear equations.

So first let's solve for x=10:

Move 10 to the other side.

As there is no y given we will simply write 0y.

Now let's solve for y=-3:

Move -3 to the other side.

As there is no x given we will simply write 0x.
