Answer:

Step-by-step explanation:
Let the fraction be
.
That would mean:
(1) x+y = 19
&
(2) y+8 = 2x or 2x = y+8
In order to use substitution, we multiply equation by 2:
(3) 2x+2y = 38
Then we substitute equation (2) into (3):
y+8 + 2y = 38
3y + 8 = 38
3y = 30
y = 10
Substitute this into equation (1)
x + 10 = 19
x = 9
Therefore the fraction would be:

The independent variable isn't affected by anything and can't change, and the dependent varible relies on the independent variable to decide what it is.
