Step-by-step explanation:
[tex]9y-\frac{1}{2}\left(4y+20\right)[/tex]
To simplify this expression, first use the distributive property to distribute [tex]\frac{1}{2}[/tex].
[tex]9y-\frac{1}{2}(4y)+-\frac{1}{2}(20)[/tex]
Simplify.
[tex]9y+-2y+-10[/tex]
Combine like terms, [tex]9y[/tex] and [tex]-2y[/tex].
[tex]7y-10[/tex]
The simplification of [tex]9y-\frac{1}{2}(4y+20)[/tex] is [tex]7y-10[/tex].
