Step-by-step explanation:

y-x=0.7

y=x+0.7, so lets plug in that into the expressions instead of y

1)

(y-x) =

x+0.7-x=

x+0.7 + (-x) =

x + (-x) + 0.7=

x-x+0.7=

0.7

2)

(x - (x+0.7)) / ((x+0.7) - x) =

(x-x+0.7) / (x+0.7-x) =

(x-x+0.7) / (x+0.7 + (-x)) =

(x-x+0.7) / (x+0.7 + (-x)) =

(x-x+0.7) / (x + (-x) + 0.7) =

(x-x+0.7) / (x-x+0.7) =

0.7/0.7=
