Okay .. do you understand the difference between variable and constant?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
variable is something you put instead of a number, right?

More importantly, do you understand what in earth an equation means?
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
Precisely, variable is something that varies, so yes you are right :)

Were you just calling me stupid?
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
No,lol :D you misunderstand my tone :) So what is an equation ?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Its a line that states values of variables, i guess
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
Hm. Let me explain.

I know, if you do something to the LHS you have to do the same to the RHS

yadda yadda, i know all that.

Hey, that's not the right attitude towards mathematics :)
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
anyways back to the problem our hand: a+b=9 a−b=11
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
we want to find a and b in terms of constants only.
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
How could we do that ?
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
constant is something which value is fixed.
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Ok, so we can subtract a from both sides to get b on the top one, right?
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
Why don't we add the equations? like this \[ a+b+ab=9+11\]
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Oh you want me to use both equations?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Well we can simplify that to a2=20, right?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Cause the b's cancel eachother out
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
And for a we can just divide both sides by 2 getting x=10
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
Good, now what about b ?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
a+b+a−b=9+11 a2 +b=20+b Am i doing alright so far?
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
no, you need to subtract this time

InopekiBest ResponseYou've already chosen the best response.2
Is is (a+b)(a+b) or without parenthesis?
 2 years ago

FoolForMathBest ResponseYou've already chosen the best response.2
second equation from the first.
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Oh i see, this si the second one?

(a+b)(ab) without parentheses
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
a+ba+b=911 2b=911 2b=2 b=1

If ax  a = x  1 what is x equal to?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
Divide both sides by x, right so far?
 2 years ago

InopekiBest ResponseYou've already chosen the best response.2
No wait, ax  a = x  1 ax=x1+a x=x1 Im stumped
 2 years ago

SimonSBest ResponseYou've already chosen the best response.0
First, bring all the x terms to one side, and everything else to the other.

InopekiBest ResponseYou've already chosen the best response.2
Im sorry, i havent studied factoring yet :/
 2 years ago

SimonSBest ResponseYou've already chosen the best response.0
Ok. Here's the solution ax  a = x  1 ax  x  a = 1 ax  x = a  1 x(a  1) = a  1 hence x = 1
