Question 71231
-5(3x-2y)-(x+6Y)

{Note that -(x+6y) is the same as -1(x+6y))

We will first get rid of the parens by applying the distributive law which states that a(b+c)=ab+ac and we get:

-15x+10y-x-6y  

Next, we will collect like terms which means that we will add x's together, the y's together and the numbers together (and there are no numbers) and now we have:

-16x+4y  

We will now apply the distributive law again (which means that we factor out a -4)  and we get:

-4(4x-y)--------------------------ans

Hope this helps---ptaylor
