y = -3x + 6\n y = 9\n what is the solution to the system of equations?\n (-21, 9)\n (9, -21)\n (-1, 9)\n (9, -1)

Answer

Explanation:

Step1: Substitute y - value

Since (y = 9), substitute (y) into (y=-3x + 6). So we get (9=-3x + 6).

Step2: Solve for x

First, subtract 6 from both sides: (9-6=-3x+6 - 6), which simplifies to (3=-3x). Then divide both sides by - 3: (\frac{3}{-3}=\frac{-3x}{-3}), so (x=-1).

Answer:

C. (-1, 9)
