Hi there! Hopefully this helps!

Answer:
\boxed{y=5}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


4y=38-(1)/(2) (4y+16)

Use the distributive property to multiply
-(1)/(2) = -0.5 by
4y + 16.


4y=38-(1)/(2) * 4y-(1)/(2) * 16

Express
-(1)/(2) * 4=-2 as a single fraction.


4y=38+(-4)/(2)y - (1)/(2) * 16

Divide −4 by 2 to get −2.


4y=38-2y-(1)/(2) * 16

Express
-(1)/(2) * 16 = -8 as a single fraction.


4y=38-2y+(-16)/(2)

Divide −16 by 2 to get −8.


4y=38-2y-8

Subtract 8 from 38 to get 30.


4y=30-2y

Add
2y to both sides.


4y+2y=30

Combine
4y and
2y to get
6y.


6y = 30

Divide both sides by 6.


y=(30)/(6)

And finally, divide 30 by 6 to get, you guessed it, 5!

Answer: y=5

Explanation:

Given

4y=38-1/2(4y+16)

Distributive -1/2 to the parentheses

4y=38-2y-8

Add 2y on both sides (addition property of equality)

6y=38-8

Combine like term

6y=30

Divide 6 on both sides (division property of equality)

y=5

Hope this helps!! :)
