Answer:

Sadi could not have scored 4 goals

Step-by-step explanation:

Let's call x the number of goals Sadie scored

Let's call v the number of goals that Connor scored

We know that together they scored 9 goals. This means that:

[tex]x + v = 9[/tex]      (1)

We know that Connor scored two times as many goals this Sadie. This is:

[tex]v = 2x[/tex]          (2)

Substitute equation 2 into equation (1) and solve for x

[tex]x + 2x = 9\\3x = 9\\x = 3[/tex]

Then

[tex]v = 6[/tex]

Connor scored 6 goals

Sadie scored 3 goals.

Sadi could not have scored 4 goals because that would mean that Connor marćo 8 goals and we know that together they added 9 goals
