Hello Everyone, I need help with the following equation:
1/2m + 1 = 5/6m -2
Cheers Valkyriel
Edit:
Need help with another one aswell
3/x-1 = 5/2x+1

Please use bracketing symbols to make it clear what the denominators are. You may know what you mean, but there is doubt, at least to me, what the intended equations are.
My bad, never really did math on computers.
First one:

Second one:

A start to both:
(m + 1) / 2 = (5m - 10) / 6
3(2x + 1) = 5(x - 1)
If you're unable to continue, you need classroom help...
I still don't get it...
Does that mean you won't help me further?Quote:

i think u need to register to see it but its worth it :) hope it help!:)
I assume that you are solving for "m"?
Original Problem:
$\displaystyle \frac{1}{2}m+1=\frac{5}{6}m-2$
Multiply and get and get common denominator.
$\displaystyle \frac{m+2}{2}=\frac{5m+12}{6}$
Can you continue from here?
Also if you use wolfram, be sure to use parentheses.
First one on wolfram
(1/2)m + 1 = (5/6)m -2 - Wolfram|Alpha
sorry i did confuse with x and m
this maybe against the forum rule but ima show u step by step how to solve one of them ( the x one)
u got
3/(x-1)=5/(2x+1)
with a law u can swap idk the name so u got
3(2x+1)=5(x-1)
now lets multiplice the parentes so we got
6x+3=5x-5
now we subtra with 5 (u take -5 on both side) and we got
x+3=-5
u want x alone so u have to get away with 3 so we do -3 both side then u got
x=-8
Now u have solved this problem!:) cheer =D hope u did understand and gl on the other problem :)
Thanks to both of you :)
Petrus, please use YOU, not U. Can be confusing, if u is a variable.Quote:

How do you think that'll help him? His teacher will think he did it by himself...
sorry im used to use "u". Sometimes you learn to see how to solve especially this is not "hard". I learned alot from see how to solve and thats what i sometimes i do. Sorry i did solve 1 and let him solve the 2Quote:

I totaly agree with u but we all know that homework is not a "big deal" for the grade. He will need to show all his skill in test so w/e done is done.. he maybe learned something now :)Quote:
