Question
how do you solve 15= -h
Hello Simone,
I'm not sure I understand the question. Do you want to find the value of h? If that is the case, the solution is very simple. You multiply both sides by "-1":
(-1)*15 = (-1)*(-h)
Then you apply the rules for signs multiplication ("minus" times "minus" gives you a "plus" on the right side). This gives you
-15 = h
so the answer is h=-15.
Was this clear? Please let me know if that was not your question.
Cheers,
David

PLEASE READ THIS BEFORE POSTING YOUR QUESTION: While I am glad to offer HELP with problems, I refuse to SOLVE problems. There is a difference. Please do not just copy a question from a texbook or assignment. I WILL REJECT IT. I will only accept questions if, in addition to the statement of the problem, you describe in detail what you have tried so far in order to solve it, and what exactly is the problem you are encountering. In other words where/why are you stuck? I can answer questions at the level of the first couple of undergraduate years (in science and engineering) or below. You can ask me about algebra, trigonometry, basic probability and statistics, calculus, vector calculus, differential equations and Fourier analysis. I will not answer advanced (at the graduate level) math questions. Questions in Spanish are also welcome.
