Help with a simple Algebra problem!!!

[luvestodizz]

My DS has to solve this

n + -10=60


Please help!! TY

 

[SweetGalSouth]

n+ -10 = 60
n = 60 + 10
n = 70
Hope this helps

I failed math - but 70?

 

[teacherforhi]

You do the opposite. Since the problem is addition, you subtract a -10 from both sides, which is the same thing as adding a positive 10.

 

[CathrynRose]

n+ -10 = 60
n = 60 + 10
n = 70
Hope this helps

Oh, you need steps.... maybe thats why I failed math.

What grade? Looks like what we are doing also.

n + -10 = 60
n + -10 (+10) = 60 (+10)
n = 70

I tell my dd that whatever you do to the one side to solve for n, you have to do the same to the other side.

 

[christiane]

I agree, the answer is 70.

 

[catycatcat4]

I was thinking it was 70 also.

 

[hulagirl87]

wow. I feel stupid. I had no idea!

ok, I just posted but then showed the question to DH and he immediately said "70". He will clearly be teaching DD math!

That's it exactly. I always tell kids that algebra is very fair that way. - It amuses them because they find it so unfair that they have to do it, but it helps them remember that whatever you do to one side, you have to do to the other.

 

[CathrynRose]

See?? Looking at all this chitter chatter about it, makes me understand WHY I failed math.

Why can't (I) just look at it, and solve it? What's with the front and back thing?? It's confusing me.

I'm so glad I'm not in school, anymore. *phew*

What does this mean????

n + -10 = 60
n + -10 (+10) = 60 (+10)
n = 70

OK, using English (my major), here's how you'd "say" it:


The problem is: n + -10 = 60
n plus negative 10 equals 60

To solve this, you have to isolate "n." Since "n" starts out being added to negative 10, you have to get rid of negative 10. To do that, you add positive 10 to it. If you add 10 to one side, you also have to add it to the other side:

n + -10 (+10) = 60 (+10)
n plus negative 10 plus positive 10 equals 60 plus positive 10.

Since the negative 10 and the positive 10 added together equal "zero," you now have n by itself on one side. The 10 you added to the 60 on the other side equals 70, so now you have solved the problem:

n = 70
n equals 70

Then, personally, I go back and stick the answer into the original equation and see if it works:

n + -10 = 60
70 + -10 = 60
Since "plus negative 10" is the same as "minus 10", the answer makes sense. 70 minus 10 does equal 60.

I hope that helps for those of us (myself included) who like to see it in words.

Makes me think of a george lopez eppisode

algebras crap,its a waste of gas,seeing your teacher sitting on her big fat,ask me how to do it and i'll tell you brother, just do one side what you did to the other,take the bottom number multiply,see what im doing im not high

this has to be a joke right? you are seeing how complicated this thread is going to get. and you and your son are laughing right now. because if you are serious, then i advise you and your son to step away from the math book right now before you seriously hurt yourselves.

Without all the steps just think


What number minus 10 equals 60?

Exactly! Did that in my head in a fraction of a second.

What grade is this for?
Can we have some difficult ones? I loved math.

 

[okeydokey]

When I taught algebra to kids, I told them that the equal sign was like the fulcrum of a see saw. If a 50 pound kid got on one side, a 50 pound kid had to get on the other side so it would still be equal.

Whatever you do to one side of the equal sign (or equation) you had to do the exact same thing to the other side or it wouldn't be equal anymore.

If you add 10 to one side you must add 10 to the other side, see?

That's what I did. I think I posted 2nd in this thread, with 70.

What's confusing me is everyone posting steps. Why are you doing that? Why are you adding to the front and the back?

Nevermind... I've been drinking. It's not gonna penetrate my brain at this point, anyways.
