Well it's always good to confirm what the OP is asking for. There are a lot of people on this site who ask their questions in a confusing way so I've just come to confirm at the start rather than later on lol

kk

Anyways, the way to go about solving this one would be to get all of the a values on one side and all of the number values on the other side.
anonymous
  • anonymous
5a+a first right
anonymous
  • anonymous
Well a is already positive on the right side, so to bring it over we would subtract it.
anonymous
  • anonymous
In other words 5a-a
phi
  • phi
you might think like this: how do I *get rid of a on the right side* ? answer: add -a but to keep things equal, you also add -a to the left side.
phi
  • phi
ok but not just 4. it is 5 a's take away 1 a.
anonymous
  • anonymous
open study whenever i get on its always acting wierd
anonymous
  • anonymous
6a
phi
  • phi
start over, and to it carefully 5a+11=a-13 add -a to both sides. what do you get? (and write out the whole equation)
anonymous
  • anonymous
hold on one sec i need to draw it and it wont let me i'm going to refresh the page.
anonymous

|dw:1439758244788:dw|
phi
  • phi
ok, except a+a is not 0 (it is 2a) try adding -a to both sides
anonymous
  • anonymous
7a then.
phi
  • phi
start over, 5a+11=a-13 add -a to both sides. Just write -a on both sides. can you do that ?
anonymous
  • anonymous
can you show me the steps to the answer i already know the answer its -6
anonymous
  • anonymous
of how you would you do it
phi
  • phi
yes, we will get the answer. I would add -a to both sides. that means write -a on both sides can you try to do that ?
anonymous
  • anonymous
can you show me in drawing of how the step would be?
phi
  • phi
you write -a on both sides , like this 5a+11 -a =a-13 - a
phi
  • phi
if we look just at the "a" part , on the right side you have 1a take away 1 a on the left side you have 5 a's take away 1 a
anonymous
  • anonymous
so its 4a?
phi
  • phi
can you write out the whole equation? start with 5a+11 -a =a-13 - a and simplify both sides. can you do that ?
anonymous
  • anonymous
yea sure one sec.
anonymous
  • anonymous
5a+-a=a-13a ? is that what i would do on the right side
phi
  • phi
you start with 5a+11 -a =a+ -13 + -a you can switch the order of the right side (if you want) to 5a+11 -a =a+ -a + -13 what is a+ -a ?
anonymous
  • anonymous
2a?
phi
  • phi
what is 1+ -1 ?
anonymous
  • anonymous
0
phi
  • phi
and 2+ -2 or 3+ -3 or a+ -a always adds up to 0
anonymous
  • anonymous
kk
phi
  • phi
5a+11 -a =a+ -a + -13 the right side, a+ -a is 0 so you get 5a + 11 -a = 0 + -13 0 + -13 is -13 , right?
anonymous
  • anonymous
yes
phi
  • phi
so far we figured out 5a + 11 -a = -13 now look at the left side. it says 5 a's and 11 and take away 1 a we can simplify 5 a's take away 1 a.
anonymous
  • anonymous
4a
anonymous
  • anonymous
no sorry 6a
phi
  • phi
ok, but try to get in the habit of writing the whole equation 5 a's take away 1 a is 4 a"s (we write it 4a) what is the whole equation?
anonymous
  • anonymous
so it is 4a?
phi
  • phi
yes. if you had 5 cows and took away 1 cow, how many cows would you have? it works the same for a's
anonymous
  • anonymous
4a+11=-13
phi
  • phi
notice if you could make the 11 "go away" you would have 4a by itself luckily we can make 11 go away. we add -11 and we have to add -11 to the other side to keep things equal write -11 on both sides.
anonymous
  • anonymous
then subtract 11to both sides 24 so then it would be 4a=-24
phi
  • phi
yes. if we do it this way: 4a+11+-11=-13+-11 then on the left we have 11+-11 which is 0 (just like a+-a is zero) and on the right side -13 + -11 is -24 so you have 4a = -24 the last step is to divide both sides by 4 \[ \frac{4a}{4} = \frac{-24}{4} \]
phi
  • phi
it might not be obvious , by 4a/4 is just a
anonymous
  • anonymous
-6 thanks
anonymous
  • anonymous
a=-6
phi
  • phi
yes. good job. if you do a bunch of these problems, it will start to make sense.
anonymous
  • anonymous
thanks again. :)
