goal=6

panalty= -10

Step-by-step explanation:

6g+3p=6.    < multipilly by -3

8g+9p= -42

-18g - 9p = -18

8g+9p=-42

= -10g = -60

goals are worth 6 points

than you would plug the 6 back in either equation

6(6)+3p= 6

36 + 3p = 6

-36.           -36

3p=-30

p=-10

so panalties are worth -10 points
