For this case we have the following system of equations:

$y = -6x + 9\\y = -3x + 3$

Equating the equations we have:

-6x + 9 = -3x + 3

Adding 3x to both sides of the equation:

$-6x + 3x + 9 = 3\\-3x + 9 = 3$

Subtracting 9 from both sides of the equation:

$-3x = 3-9\\-3x = -6$

Dividing between -3 on both sides of the equation:

$x = \frac {-6} {- 3}\\x = 2$

We look for the value of "and":

$y = -3 (2) +3\\y = -6 + 3\\y = -3$

Thus, the solution of the system is (2, -3)

Answer:

(2, -3)
