The first one is porportional the second one is not. We can figure this out by trying to figure out a pattern between the relationships.

6-4

12-8

24-16

We can see that the proportional relationship in the first one is 3-4, because if we divide each left one by 3 and the second one by 2, the number will be the same!

MatroZZZ [7]

Answer:

C

Step-by-step explanation:

7x + 3y = 30 (equation 1)

-2x + 3y = 3 (equation 2)

9x = 27 (subtract the two equations to eliminate y)

x = 3 (divide by 9)

7 * 3 + 3y = 30 (Substitute x = 3 into equation 1, it doesn't matter which equation you substitute into)

21 + 3y = 30 (7 * 3 = 21)

3y = 9 (Subtract 21)

y = 3 (divide by 3)

Answer is (3, 3)
