2)

Simplify - 2 (x + 4) + 5x + 10

First distribute through the set of parentheses.

When we distribute, we multiply the number outside

times each of the terms located inside the set.

So we have - 2 (x) + - 2 (4) or - 2x - 8.

Now we have - 2x - 8 + 5x + 10.

Combine like terms → your numbers and your "x" terms.

-2x + 5x is 3x and - 8 + 10 is 2.

So we have 3x + 2.

3x + 2 cannot be simplified any further.
