Answer:
x = (-(10*y+10))/2
Step-by-step explanation:
x in (-oo:+oo)
6*x-((2/3)*(6*x-(15*y))) = -10 // + 10
6*x-((2/3)*(6*x-(15*y)))+10 = 0
(-2/3)*(6*x-15*y)+6*x+10 = 0
6*x-2/3*(6*x-15*y)+10 = 0
6*x-2/3*(6*x-15*y)+10 = 0
2*x+10*y+10 = 0
2*x+10*y+10 = 0
2*x+10*y+10 = 0 // - 10*y+10
2*x = -(10*y+10) // : 2
x = (-(10*y+10))/2
x = (-(10*y+10))/2
"Porportional Relationships" means that the rate in which it increases is the same.
For example: 1, 3, 5, 7, 9 is a porportional relationship, because it increases each time by (+2).
Now, look at the first one.
From y to x, y being 2, x being 10, you divided 5 from x to get 2. Next, you divided 6 from 30 to get 5. Because the number dividing is different, it is not proportional

Look at the second one.
From y to x, y being 12, x being 10, you divided 1.2
Now, look at the next one. 30/25 = 1.2
Finally, the last one. 48/40 = 1.2
Because all of them are 1.2, the answer is proportional
