Hi,

Im new to this forum, so I hope im i line with posting correctly and everything.

Ive totally forgot how to solve simple equations:(

(100 - S) = 8,042 * S,

How would one solve this?

Thanks in advance.

Oh, I think I figured it out myself. Unfortunately in my case, math is forgotten over time:(

8,042 * S = S - 100 ((adding S)

9,042S = 100

S = 100/9,024

S = 11.06 - Sep 17th 2011, 07:26 PMWilmerRe: Simple equation solving
Back to school, Desperado?

Seems like you're trying to play hockey without skates (Wink)

Lets do one similar to yours:

10 - 2a = 803a (2a means 2 * a, 803a means 803 * a)

add 2a to both sides:

10 - 2a + 2a = 803a + 2a

10 = 805a ...still with me?

now wrap up:

a = 10/805

a = .01242...

Now go do yours similarly... - Sep 18th 2011, 12:25 AMmr fantasticRe: Simple equation solving

This is not your original problem. Your original problem was 8,042*S= 100- S. For the original problem, adding S is correct and you get

Quote:

9,042S = 100

**didn't**"add S", you added 1000 S!

Quote:

S = 100/9,024

S = 11.06

Added in second edit: But then why did you use '.' in your final answer?

The correct answer is**either**11,08 (NOT 11,06) if you are using the "," to separate whole number from decimal part or 0.011 if you are using "." with "," separating thousands. - Sep 18th 2011, 10:14 AMdesperadoManRe: Simple equation solving
Yea back to schoo. And im not going to say what course im studying, after asking for this problem:)

I did yours, and mine the same way as how Mr-fantastic said. Donno why, just forgot it:( - Sep 18th 2011, 10:20 AMdesperadoManRe: Simple equation solving
