# What could be the solution to this? [closed]

I am sorry people but can you tell me the answer to this ?

This is the question, just this.

-3(2a-4) | Answer format: 90a+30 (with other numbers):

Multiply out / resolve the parentheses? – Hagen von Eitzen Oct 18 '12 at 21:02
I don't think all the negative votes are all that necessary here. Yes, the question is very unclear. But that's actually what OP is asking for help with; trying to make sense of something that is unclear that someone else put in front of him/her. – alex.jordan Oct 18 '12 at 22:08
:) Ok this is the solution = -6a+12 I didn't solve this ofcourse,but this site (online algebra solver) did,algebra.com :) – gexos Oct 19 '12 at 18:27

Someone is asking you to distribute the $-3$. The final answer to that question will look like $$90a+30$$ but the 90 and 30 will be replaced with different numbers.
 Thank you for the answer alex, maths is not my thing :( this is from a forum that asks this for registration. i could provide the link if it is ok. anyway thank you gave me a clue :) – gexos Oct 18 '12 at 21:09 Here's a clue. For your purposes, the distributive law states that for any numbers $a, b, c$ it will be true that $a(b+c)$ will be equal to $ab+ac$. That's what you're required to do: (1) identify the $a, b, c$ in the problem and use the distributive law to get a result in the form needed. There's a lot of that in mathematics--identifying a pattern in a problem and recognizing that it's similar to another. One might even say that that's what most mathematics research is. – Rick Decker Oct 18 '12 at 23:16 Thank you too Rick, – gexos Oct 19 '12 at 18:12
