Hello! I need to solve the following equation:

f(x)←(x/FractionTSS_ade_l+(TSSm_ade-x)/FractionTSS_ade_s)-Qm_ade

x←1000*'kg/'day

TSSm_ade_l←root(f(x),x)

TSSm_ade_l=#@'kg/'day

But can not get any correct answer. Can I use the root function?? or is there any other function that I should use?

Thanks for your help,

Adriana

Adriana,

It appears your function is a straight line. There are no roots.

a=FractionTSS_ade_l

b=TSSm_ade

c=FractionTSS_ade_s

d=Qm_ade

x/a + (b-x)/c -d = 0

x(1/a - 1/c) + (b/c - d) = y or y=mx+b m=slope, b=y intercept
