What is - 2 (x+5) = 4?

Multiply - 2 and x, and you'll have - 2x. Then multiply - 2 and 5, and you'll have - 10. Therefore, - 2x-10=4, but we're not done yet. We need to get x by itself, so what we're gonna have to do is add 10 to both sides. Now you'll have - 2x=14, and when you divide both sides by - 2, you'll have x=-7 which will be your answer
