Which equation represents "the sum of eight times a number and seven is twice the number"?


8(7 + 2N)
8N = 7 + 2N
7N + 8 = 2N
8N + 7 = 2N

Answer 1

8N + 7 = 2N

Answer 2

8n+7=2n

Answer 3

Thanks guys!

Answer 4

lol

Answer 5

hahah that sucks!

Answer 6

Why is there a"+" sign after the fraction

Answer 7

That's how it says for my school work

Answer 8

ohhh wait after the "+" it's a 3 so it would be +3=27

Answer 9

If the + sign holds no significance you would simply multiply the 4 on both sides leaving you with 3x = 108 and then you divide the 3x by 3 and do it to both sides both isolating the variable and receiving your answer.

Answer 10

So what your saying is it's: \[3x/4 + 3 = 27\]

Answer 11

so 3 x 108?

Answer 12

so 32?

Answer 13

let me write this down.

Answer 14

Except for the fact that you left out the +3, so you will have to redo exactly how you did, but first you must subtract the three from both sides before anything.

Answer 15

idk. I'm lost and this is why I hate math lol.
