Answer:
c is the answer
Step-by-step explanation:
Based on the given fractions above which are 7/8 and 42/4, in order for us to know if they are both proportional is to do the cross multiplication. Let's say, we multiply 4 by 7 and we get 28. Divide 28 by 8 and the result is 3.5 and not 42. Therefore, we can say that these fractions are NOT proportional. Hope this helps.

Answer:
2
Step-by-step explanation:
10x + 2y=42
(5x +y=20) x2
so we get
10x+2y=42
10x+2y=40
Using ELIMINATION METHOD WE GET-
=2
