Solve for y for these equations??? Plz help and thnks?

Question

1) x-2y=1

2) 2/3y+ k=j

3) 5(2a+y)=3b

4) 2/3y+a=a+b

Answer 1

①

Y = (x-1)/2

②

Y = 2/3(j-k)

③

Y = (3b-4a)/5

④

Y = 2/(3b)

Just answered them the way I see them. I don't know how you intended to write the fractions, so I just did them the way I can see them.. I hope its the correct interpretation.

Answer 2

(x-1)/2 = y

2(j-k)/3 = y

(3b-10a)/5 = y

3/2b = y
