wsyan.
6000x(5.5%-R%)x2=180
6000x(5.5%-R%) = 90
330- 6000R% = 90
330-90 = 6000R%
240 = 6000R%
240/6000% = R
R= 4
6%x73y
----------- = 13156-y
365
6%y / 5 = 13156-y
6%y = 65780-5y
6%y+5y = 65780
5.06y = 65780
y = 13000[color=beige]

Athena`
1.6000x(5.5%-R%)x2=180
5.5% -R% = 180/2/6000
0.055- R/100 = 0.015
-R/100 = -0.04
R/100= 0.04
R = 4
2. 6%x73y
----------- = 13156-y
365
0.06 X 73y = 4801940 - 365y
4.36y = 4801940 - 365y
369.36y =4801940
y = 13000
