.08C+.06B=84
WITHOUT ANY ADDITIONAL INFORMATION YOU HAVE ONE EQUATION WITH 2 UNKNOWNS WHICH WILL NOT YIELD A UNIQUE SOLUTION.
THERE ARE ALMOST AN INFINITE NUMBER OF POSSIBLE SOLUTIONS HERE.
EXAMPLES:
LET C=1000 & B=66.67
.08*1000+.06*66.67=84
80+4=84
84=84
OR:
B=500
C=675
675*.08+.06*500=84
54+30=84
84=84
