Answer:
21
Step by step explanation:
So, what we know is that we have 3 field goals, each worth 3 points, and 2 touchdowns, each worth 6 points. So we can do: 3 * 3 + 2 * 6. To break this down we first must do 3 * 3. This gets us an answer of 9, we then must do 2 * 6. Which gives us an answer of 12. Now that we have multiplied the 2, we may add, 9 + 12 = 21. Meaning our answer is 21. I hope this helped you out!

2x + 4 = x - 4
2x - x = -4 - 4
x = -8
Solution: x = -8
