One half of 4 times y plus the quantity of y and 3?

It's pretty confusing, but I think that means:

"one half of 4y..."
½*4y

"...plus the quantity y and 3."
½*4y + (y + 3)

Multiply ½ times 4:
2y + y + 3

Combine the like terms:
3y + 3

Answer:
3y + 3

One half of 4 times y plus the quantity of y and 3?

So:
(4y / 2) + (y + 3)
That means:
2y + (y + 3)
Comes to:
3y + 3

1/2 * 4y + y + 3 = 2y + y +3 = 3y + 3 or 3 ( y + 1 )

Depending on how you interpret the question:

2y + y+3 = 3y + 3

or

(1/2)(4y + y + 3) = (5y+3)/2

0.5 * (4*y) + (y+3)
2 + 0.5 (y) + y + 3
5 + 1.5 ( y)

7 of y plus 3
