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:

\(y = -3x + 6\)


\(y= 9\)

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 \(y = -3x + 6\)

\(9 = -3x + 6\)

Subtract 6 on both sides

\(9-6 = -3x + 6-6\)

\(3 = -3x\)

Now divide both sides by -3

\(x=-1\)

The value of \(x=-1, y=9\)
