Question

-(-6w+v)+2(v+6w)

Answer 1

distributive property
with the portion -(-6w+v) assume that there's a 1 after the first negative
so it looks like this -1(-6w+v) ...

Answer 2

an example of a distributive property would be

-3(a + 6b) = -3a -18b

Answer 3

-(-6w + v) = 2(v + 6w) -- distribute through the parenthesis
6w - v = 2v + 12w -- subtract 12w from both sides
6w - v - 12w = 2v -- add v to both sides
6w - 12w = 2v + v -- combine like terms
-6w = 3v
w = - 1/2v or v = -2w
