I am unable to solve the two simultaneous equations: 0.991=0.0266x+0.0835y, 0.325=0.0499x+0.0077y. Could you help?
Use the fisrt equation to find y=f(x) on replace the y's expression found in the second equation to compute x and you'll find y (I have x=0.523...)
if i were doing it i would clear the decimals and write \[266x+835y=9110\] \[499x+77y=3250\]
then i would go slap the math teacher for giving me such annoying numbers to work with. then i would use some computer algebra system to solve
well not that hard when you ask the machine. i got \[x=\frac{ 1950680}{396183} \]
how much arithmetic do you wan to do for a problem like this?
The thought police will be after u for suggesting an assault on apoor math teacher...
ok a mild slap with a kleenex. but really, who would even want to know such a thing. if this problem arose naturally from some actual data, then fine. get out the software and find your answer.
Either u or olive is a bit out...
i used a machine. i have no stake in this game
I guess olive used her machine wrong, I'm not going to check it though.
She got the principle right, that's the main thing...
Thanks for your help. By the way, this is chemistry...determining unknown concentrations.
That's a reasonable excuse, no need to slap the chem teacher, then:-)
