This is my attempt:

yes=x

no=y

y=x + 1 000 000

2 y = x + 1 050 000

This is however incorrect. Where is my error? I know how to solve simultanious equations and I only need help with writing the first to equations. Thank you in advance!

The 2 should be on the other side. Thank you for your help! Soroban has also send me an email and explained how to do it.tkhunny said:2(y+50000) = (x - 50000)

I already spent some time in the corner, so no one suggest it.

1) You actually could have done it yourself, otherwise you couldn't have known that my original equation was wrong.

2) You still waited for someone else to show you how to do it, even though you knew already, rather than figuring it out for yourself.

3) Soroban is acting subversively to undermine the efforts of other volunteers, rather than his usual M.O. of just providing complete public solutions that require nothing from the student.

Does ANYTHING about this seem reasonable to you?

2) No I did not know it. When I logged in I had an answer from you and from soroban and I read both of them.

My only aim is to learn and understand as much mathematics as possible. The original math question was not a homework, I went to the libary and borrowed a few books so I can prepare for my exam.

often much easier if you "make up" a simpler but similar problem to the one you're given; like:

y = yes voters

n = no voters

n = 270

y = 150

OK: n = y + 120 [1]

SO: In a referendum the no alternative got 120 more votes than the yes alternative.

Now "move enough" to leave n = 2y:

n + 10 = 280

y - 10 = 140

OK: n + 10 = 2(y - 10) [2]

SO: If 10 of the yes voters had voted no , then the no alternative would have gotten twice as many votes as the yes alternative. How many participated in the referendum?

To solve, substitute [1] in [2]: y + 120 + 10 = 2y - 20 ; y = 150 ; so n = 150 + 120 = 270 ; total = n + y

Now go back to original problem: it'll be just as easy; get my drift?
