A + b+c=2,350,000..…………………. 1 .12a+.10b+.08c=220,500.............. 2 condition: c=2a...............................................3 therefore you have 3equation and 3variables, please manipulate to come up a respective value for this 3 linear system..gud luck
1 3 1
i dont know how to solve it....
from eq 1;
a+b+2a=2,350,000 or 3a+b=2,350,000.......4.); .12a+.10b+.08(2a)=2,220,500 or .28a+.10b=220,500........5.)plea se continue equating 4 and 5....
