Let the 2 numbers be x and y
x+ y = 35
let the larger number be x
3x = 4y
y = 3x/4
so,
x + 3x/4 = 35
7x/4 = 35
x/4 = 5
x = 4*5 = 20
so the larger number is 20.

'Cancellation' means to divide the numerator (top) and the denominator
(bottom) of a fraction both by the same number.
That operation is used to 'simplify' a fraction (reduce it to lower terms).
When there is no number that goes into both the top and bottom numbers,
then the fraction is in simplest form (lowest terms).
