1/y + 3/2y = 1/2
is that 3 divided by 2y or 3/2 *y ?
IE:
1/y + (3/2)y = 1/2 ALSO written as 1/y + (3y)/2 = 1/2
OR
1/y + 3/(2y) = 1/2

1/y + 3/2y = 1/2
multipy each fraction by 2y to clear the equation of fractions
2y(1/y)+2y(3/2y) =2y(1/2)
Final answer:
y=5
Hope I helped!

Multiply each side of the equation by 2y. You then get 2 + 3 = y. y = 5.

First you want to find a common denominator of 2y. So multiply (1/y) by 2 on the top and bottom (essentially multiplying by 1). Next you can combine the fractions to get (5/2y)=1/2. Next cross multiply to get 2y=10. so y=5

1 + 3 = 1
-- ---- ---
y +2y = 2
No, it will equal 5/2, because 2 will be your common denominator.

y = 5.

first you get rid of the denominator...by multiplying by the LCD or
2y
this will leave u with
2+3=y
simplify and u will get
5=y or y=5

y = 5
multiply by y in each term. then divide by 1/2 (essentially multiply by 2) in each term.
