$10 x - 15$ $10x-15$

In order to simplify $7 x - 3 (5 + x)$ $7x-3(5+x)$

We begin with the distributive property and multiply 3 to each term inside the parenthesis.

$7 x - 3 (5) + 3 (x)$ $7x-3(5) + 3(x)$

$7 x - 15 + 3 x$ $7x-15 +3x$

Now we can combine like terms

$7 x + 3 x - 15$ $7x +3x -15$

$10 x - 15$ $10x-15$
