Substitute the 1st equation in the 2nd, we get:
3x + 2(-3 + 2x) = 2
3x -6 +4x = 2
7x = 8
x = 8/7
Replace x = 8/7 in equation 1,
y = -3 + 2(8/7) = -3 +16/7 = -5/7
9:4:5.....added together = 18
9/18 (72) = 648/18 = 36
4/18 (72) = 288/18 = 16
5/18 (72) = 360/18 = 20
so we have 36:16:20

Answer:
The type of association between x and y are inversely proportional
Step-by-step explanation:
Solution:
Here the x value increase, the y value decrease which implies that x is inversely proportional to y
