Answer:

It has one solution

Step-by-step explanation:

y = x-3 equation 1

3y-3x = -9 equation 2

Substitute x -3 in place of y in equation 2.

We have

3(x-3) -3x = -9

Distribute

3 x x 3x-3 -3x = -9

3x - 9 - 3x = -9

It can also be written as

3x - 3x - 9 = - 9

Add nine to both sides

3x - 3x -9 + 9 = -9 + 9

0 + 0 = 0
