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 \[266x+835y=9110\] \[499x+77y=3250\]

    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.

    I guess olive used her machine wrong, I'm not going to check it though.
