Alright, first you subtract the 7 on both sides. So, -n + 7 - 7= 12 - 7
anonymous
  • anonymous
I did that
anonymous
  • anonymous
Confused what to divide by
anonymous
  • anonymous
and then, your final answer will be -n = 5. You don't divide in this type of problem since it is only a single variable.
anonymous
  • anonymous
So n=s just 5
anonymous
  • anonymous
-n = 5. So yeah, that's just it.
anonymous
  • anonymous
Here's another one m over 2 + 5 =s -3
anonymous
  • anonymous
First, add the 2 and the 5 so you get 7= s - 3.
anonymous
  • anonymous
And then you add the three on both sides, so 7 + 3 = s -3 + 3. And then you get 10 = s
anonymous
  • anonymous
So add 5+2 an 3+2
anonymous
  • anonymous
No, you add the the 5 and the 2 to get 7 and then your new equation is 7= s - 3
anonymous
  • anonymous
So you do 5-5 since add isnopposite
anonymous
  • anonymous
What u add both sides with?
anonymous
  • anonymous
you add 3 to both sides, 7 + 3 = s - 3 + 3
anonymous
  • anonymous
You're trying to get the variable by itself. So then you get 10 = s and that's it
anonymous
  • anonymous
So add th my subtract
anonymous
  • anonymous
I got 8 5+3 is 8
anonymous
  • anonymous
U not suppose to subtract instead of add cuz I thought you was suppose to do the opposite of the sign
anonymous
  • anonymous
I think you're a bit confused, which is okay. 2 + 5 = s - 3 7 = s - 3 add 3 to both sides: 7 + 3 = s - 3 + 3 10 = s
anonymous
  • anonymous
So I added 5+2 which is 7 what is the next addition problem
anonymous
  • anonymous
I'm suppose to marooned addition part of it out cuz it's suppose to equal 0 or be the same number than u just mark it out
anonymous
  • anonymous
I got 5+2 down just confused on what else I'm suppose to add 2 with
anonymous
  • anonymous
the 5 + 2 was part of the original equation so you don't add it to anything else you just simplify it so it equals 7
anonymous
  • anonymous
Ok what r u suppose to divide it by?
anonymous
  • anonymous
If u didn't simply it what would you have to put down next to the 5+2 what other problem
anonymous
  • anonymous
There's no division required since it's just a single variable
anonymous
  • anonymous
So m=s 7
anonymous
  • anonymous
10 = s You want to find the value of s
anonymous
  • anonymous
and s = 10
anonymous
  • anonymous
There isn't a s on here tho loll hers no other letter but m
anonymous
  • anonymous
2 + 5 =s -3 that was the original equation you asked.
anonymous
  • anonymous
No m over two means divide + 5=a-3
anonymous
  • anonymous
=-3 not a-3
anonymous
  • anonymous
I'm not sure what you're talking about anymore, I think my work here is done.
anonymous
  • anonymous
An I'm trying to find m
anonymous
  • anonymous
Okay thanks
