8k-1=15 ? Help I have a question were we have to work this out what do I do?

Answers

Answer 1

Answer: $8k-1=15\ \ \ \ /+1\n\n8k-1+1=15+1\n\n8k=16\ \ \ \ /:8\n\n8k:8=16:8\n\nk=2$

Answer 2

Answer: you have to add 1 to the -1 and you will get 0.What you have to do next is also add 1 to 15 because you want a variable on one side and a number on the other.So now you have 8k=16. So you divide 8 to 8k and you get nothing divide 8 and 16 and your answer for k =2 hope you get it right.trust mw it is very easy when you get use to it

The easyiest but not the only, way to solve this problem is the FOIL method. You first do a*a=a^2 then a*-2=-2a then a*3=3a then 3*-2=-6 then you add it all together a^2-2a+3a-6 then simplify. so the answer is a^2+a-6! Any more questions?
