Best ResponseYou've already chosen the best response.0do the brackets mean anything and you do know you have two equal signs right?

Best ResponseYou've already chosen the best response.0is this some kind of algebra or something more exotic,and as freckles said do the brackets have some special you know meaning

Best ResponseYou've already chosen the best response.0i think i wrote it wrong it's supposed to be a [bx c] = d

Best ResponseYou've already chosen the best response.0welll okay I would divide both sides by a first isolating the thing in brackets

Best ResponseYou've already chosen the best response.0and put a little note on the side I suppose saying assuming a is not 0

Best ResponseYou've already chosen the best response.0bxc=d/a then just undo the subtract by c by adding c on both sides

Best ResponseYou've already chosen the best response.0and then divide both sides by b making an assumption that b isn't 0

Best ResponseYou've already chosen the best response.0i did this a [bx  c] =d divide both sides by a then [bx c] =da bxc =da then i add c on both sides bx=da+c over b x=da + c over b

Best ResponseYou've already chosen the best response.0if you divided both sides by a then why does it show you divided a on one side and multiplied a on the opposing side?

Best ResponseYou've already chosen the best response.0\[a(bxc)=d \\ \\ \text{ divide } a \text{ on both sides assuming } a \neq 0 \\bxc=\frac{d}{a} \\ \text{ adding } c \text{ on both sides } bx=c+\frac{d}{a} \\ \text{ now dividing } b \text{ on both sides assuming } b \neq 0 \\ x=\frac{1}{b}(c+\frac{d}{a})\]

Best ResponseYou've already chosen the best response.0if i divide it, i have to put it as a fraction then?

Best ResponseYou've already chosen the best response.0things you divide by are things that go in the bottom like pretend we have m=3 and we wanted to divide both sides by 2 you can write that as: \[\frac{1}{2}m=\frac{1}{2}(3) \\ \text{ or } \frac{m}{2}=\frac{3}{2}\]
