Answer 1

i don't know what the sum is, but you can get your answer with algebra

simply make one number 'x'
and one number 'y'

larger no: x
lesser no.: y

then form two equations with what you're given
x+y=[ungiven sum] --- (1)
2x-y=7 --- (2)

for (2), make y the subject as such
2x-y=7
-y=7-2x
y=2x-7

then substitute it into (1) to find 'x'
x+(2x-7)=[ungiven sum]

since x is the larger number, you would've gotten your answer^^
