Solution

The correct option is B $7 y - 3 x$
$Need to Simplify: - -------------------- -$ $3 (x + 5 y) - 6 x - 8 y$

$3 (x + 5 y) - 6 x - 8 y$
Removing the brackets,

$= 3 x + 15 y - 6 x - 8 y$
Combining the like terms together,

$= (3 x - 6 x) + (15 y - 8 y)$

$= - 3 x + 7 y$

$= 7 y - 3 x$

As a result, simplified form of the $3 (x + 5 y) - 6 x - 8 y$ is $7 y - 3 x - ------ -$ .

Therefore, option (b.) is the correct answer.
