please answer to ques. 21 urgently

Answer 1

I'm getting this answer...is this right?

Answer 2

(y+7)/3 = 1+ (3y-2)/5

or, (y+7)/3 = {5+(3y-2)}/5

or, (y+7)/3 = (5-2+3y)/5

or, (y+7)/3 = (3+3y)/5

or, 5(y+7) = 3(3+3y)

or, 5y + 35 = 9 + 9y

or, 35-9 = 9y-5y

or, 26 = 4y

or, y = 26/4

or, y = 13/2

Answer--> y = 13/2
