Question

How do you factor 8x+56?

Answer 1

If you mean how do you get x by it's you divide both sides by 8, to cancel out the multiplication between x and 8, meaning that it would end up being x=7, sorry if that didn't answer your question correctly. 

Answer 2

Divide 56 by eight (=7)
Divide 8x by eight (=X)
So you have X + 7
So I think it would be 1(x+7)

(I could be wrong)
