$9 y - 8$ $9y-8$

Explanation:

The first step is to distribute the brackets.

$\Rightarrow \frac{1}{4} (6 + 20 y) - \frac{1}{2} (19 - 8 y)$ $rArr1/4(6+20y)-1/2(19-8y)$

$= \frac{6}{4} + 5 y - \frac{19}{2} + 4 y$ $=6/4+5y-19/2+4y$

collecting like terms.

$9 y + \frac{3}{2} - \frac{19}{2} = 9 y - \frac{16}{2}$ $9y+3/2-19/2=9y-16/2$

$\Rightarrow 9 y - 8 is the simplification$ $rArr9y-8" is the simplification"$
