Suppose that: (x-(x-y))-((x-y)-x)=14 what is x

x = 0.

Step-by-step explanation:

(x-(x-y))-((x-y)-x)=14

Remove the parentheses from the inside out:

(x - x + y) - (x - y - x) = 14

x - x + y - x + y + x = 14

x - x - x + x + 2y = 14

0 + 2y = 14

x = 0 and y = 7.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

both equations and proportions are better.
