Question

What is the solution to the system of equations?
y=-3x + 6
y= 9
O (-21,9)
O (9,-21)
0 (-1,9)
O (9.-1)

Answer 1

Answer:

(-1,9)

Step-by-step explanation:

y=-3x + 6

y= 9

Set the two equations equal

-3x + 6 = 9

Subtract 6 from each side

-3x+6-6 = 9-6

-3x =3

Divide by -3

-3x/-3 = 3/-3

x =-1

y = 9

(-1,9)

Answer 2

-1 9

Step-by-step explanation:

$9 = 3x + 6 \\ 3x + 6 = 9 \\ 3x = 9 - 6 \\ x = 3 \\ x = 3 \div 3 \\ x = 1 \\ y = 9$
