Roger: Hello Jack,
Whatcha doing
Whats the Question
No the Answer is not -6n+15 it is -4n+15
I will show you how to get the answer now
First, You have to regroup the variables. Which are n and -5n
Second you have to rewrite the question so it reads n-5n+3+12
Third you put buckets under the 2 terms
Fourth you now answer what is in the buckets, which is n-5n=-4n
next it is +3+12=+15
Now you rewrite the question again and it should say this: -4n+15



Jake: Hey Roger
I'm just working on my math homework .Its Algebra and its hard.
I need help. Do you know how to answer this question Roger.
The question is n+3-5n+12
I think the answer is -6n+15
How did you get that.
Thanks Roger now I get It

Hello Jake,
Whatcha doing
Whats the Question
No the Answer is not 12n + 10. It is 12n+32
I will show you how to get the answer now
First, you have to multiply 4 by 3n. Which equals 12n
Second You need to multiply 4 by +8. Which equals +32
Finally you put both together and it should say 12n+32

Hey Roger
I'm just working on my math homework .
Its The Distributive Property and its hard
I need help. Do you know how to answer this question Roger.
The question is 2 + 4(3n+8)
I think the answer is 12n + 10
How did you get that.
Thanks Roger now I get It

One step Equation Solving

Additive:

To do a additive equation you have to know the steps or (rules).
First you write out your question, the question I choose was n-3+5=10
Second you have to clean up the junk in the question.
To clean the junk up you put these |______| under the the two constants -3 and +5.

Subtractive

To do a subtractive equation you have to know the steps or (rules).
First you write out your question, the question I chose was n-(-5)=17Second you have to clean up the junk in the question.
To clean the junk up you change the - signs both to + signs
After you have done that it should say n+5=17 or n+(+5)=17.
The third step is adding the opposite, and in this case the opposite of +5 is -5.
Whatever you do to the front you have to do to the back(answer), make balance.
Fourth is you cancel out the zero pairs, which leaves you with n= on you left and 17-5 on your right.
Now you have to answer 17-5=12. N = 12

I will now show you how to Verify:
First you rewrite the question: n-(-5)=17 or n+5=17
Second you substitute the 12 for n.
Then it should say:12-(-5)=17 or 12+5=17
The final step is 17=17

Multiplicative

To do a multiplicative equation you have to know the steps or (rules).
First you write out your question, the question I chose was 12n=180

Second you have to divide 12n by 12. Which gives you n.

Whatever you do to the front you have to do to the back(answer), make balance. Now you have to answer 180 divided by 12. Which leaves you with n= on you left and 15 on your right. N=15

I will now show you how to Verify:
First you rewrite the question: 12n=180

Second you substitute the 15 for n. It should look like this 12(15)=180

The final step is 180=180

Divisive

To do a divisive equation you have to know the steps or (rules).
First you write out your question, the question I chose was n divide 6 =6

Second you have to multiply 6n by 6. Which gives you n.

Whatever you do to the front you have to do to the back(answer), make balance.

Now you have to answer 6 multiplied by 6. Which leaves you with n= on you left and 36 on your right. N=15

I will now show you how to Verify:
First you rewrite the question: 12n=180
Second you substitute the 15 for n. It should look like this 12(15)=180
