since y is 9, we can just sub it in the first equation,
9 = -3x + 6
3 = -3x
x = -1
so the answer is the third one

Answer:

(-1,9)

Step-by-step explanation:

[tex]y = -3x + 6[/tex]

[tex]y= 9[/tex]

To find out the solution we substitute the value of y in the first equation

given y =9

we plug in 9 for y in the first equation [tex]y = -3x + 6[/tex]

[tex]9 = -3x + 6[/tex]

Subtract 6 on both sides

[tex]9-6 = -3x + 6-6[/tex]

[tex]3 = -3x[/tex]

Now divide both sides by -3

[tex]x=-1[/tex]

The value of [tex]x=-1, y=9[/tex]
