2x +3x + 25 = 5x - 15
5x + 25 = 5x - 15
5x - 5x = -15 - 25
0 ≠ -35

x=3
Answer
Find out the what is the value of x when y = 8 .
To prove
As given
The variables y and x have a proportional relationship.

y = kx
Where k is the constant of proportionality.
As y = 5 when x = 4
Put in the above
5 = 4k

Now find out the value of x , when y = 8


x= 6.5
Therefore when y = 8 than x = 6.4
Answer:
Well, 4 doubled is 8, and with a unit rate it would be 8/1!
