Answer 2

i get that part, but the rest is confusing :(

Answer 3

Ok, so it seems you're going to try to get X on one side to get the answer so you'd get rid of the Y (substitute it) and work out the math :)

Answer 4

Let me know if you can do the math, or I can go ahead and help you out a bit more. To be honest I got the answer from a quick google search so I have another link too lol

Answer 5

42=8x-14
42+14=8x-14+14
56=8x

56/8=8x/8
7=x, see like this makes no sense to me

Answer 6

Well you got the steps right and that is the right answer so are you asking HOW does that prove the answer is 7...instead of any other answer? -.-

Answer 7

no no, like how would I write that out into columns

Answer 8

ahhhh ok lol well for the written part I'd start with writing the given information so you could put something like:

1.) Y=6 Given
2)X=8 Given
3)42+14=8x-14+14 Isolate the X variable
4)etc
5)etc

Answer 9

Just explain what you did for each step

Answer 10

7y=8x-14;y=6 = given

Answer 11

Answer 22

As you got: 7y=8x-14
plug in the value of y=6

then : (7*6)=8x-14
42=8x-14
4214=8x
7=x
