Best ResponseYou've already chosen the best response.2More importantly, do you understand what in earth an equation means?

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

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

Inopeki

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

Best ResponseYou've already chosen the best response.2A equation has two parts, right hand side and left hand side.

FoolForMath

Best ResponseYou've already chosen the best response.2Anything right of the '=' sign is right hand side

Best ResponseYou've already chosen the best response.2I know, if you do something to the LHS you have to do the same to the RHS

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

FoolForMath

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

FoolForMath

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

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

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

FoolForMath

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

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

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

Inopeki

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

Inopeki

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

FoolForMath

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

Inopeki

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

FoolForMath

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

Inopeki

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

FoolForMath

Best ResponseYou've already chosen the best response.2second equation from the first.

Inopeki

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

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

Best ResponseYou've already chosen the best response.0If ax  a = x  1 what is x equal to?

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

Inopeki

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

SimonS

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

Inopeki

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

SimonS

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