Answer 1

you can cross multiply here
3(7 + n) = 43 + n
now its straight forward to solve for n

Answer 2

Is it like solving for n?

Answer 3

yes

Answer 4

So would that be like using the Distributive Property because you distribute 3 to 7 and n which would equal to 21+n

Answer 5

3(7+n)=43+n (==) 21+3n=43+; (==)3n-n=43-21(==)2n=22 donc n=11
