Answer 1

We can write the fraction as x / y, where:

x = y - 4

y + 1 = 8(x - 2)

So we start solving for y:

y + 1 = 8(x - 2)

y + 1 = 8x - 16

y = 8x - 17

And then we substitute "8x - 15" for y:

x = y - 4

x = 8x - 17 - 4

x = 8x - 21

-7x = -21

x = 3

Then we substitute 3 for x:

x = y - 4

3 = y - 4

y = 7

The fraction is 3/7.
