8%x+2%x+0.5%=356.07

0.1x=356.07-0.005

0.1x=356.065

x=3560.65

8%x+2%x+0.5%=356.07

10%x=356.07-0.005

0.1x=356.065

x=3560.65

8%x+2%x+0.5%=356.07

8x+2x+0.5=35607

10x=35607-0.5

10x=35606.5

x=35606.5/10

x=3560.65

8%x+2%x+0.5%=356,07

解；方程两边同乘以1000得;

80x+20x+5=356070

移项，合并同类项得；

100x=35665

x=356.65

可得出x=3560.65
