Chump 2a+c=0 anubiss thats itthere should be at least one known variable Chump 2a+c=1ermcan you please give me a hint .. this stuff i haven't seen it in a while hehe Steve|Office chump: AB = C, so B = A^-1 C.Compute A^-1, multiply with C and you're done. karrotx quick, someone teach me how to prove by inductionheh Steve|Office Alternatively, solve 4 simple equations.karrotx: Er, no. karrotx i've spent the most part of today trying to figure it out Steve|Office Prove P(0), prove P(n) => P(n+1). Bam! karrotx Steve|Office: yup i know that Steve|Office So then you're done.What more do you need? anubiss you know all then karrotx i can't relate p(n+1_) back to p(n) anubiss thats an algebra problem then Steve|Office Well, that's a specific problem. anubiss :) Steve|Office It need not be algebra. anubiss . karrotx i feel like i should take a college level algrebra classbut i dont think i'll really learn somoethingand by algebra i mean, low level algebra anubiss whats low level algebrawhats high level ?
