C+1.5×(16%-C)= 21%
C+1.5×0.16-1.5C = 0.21
-0.5C = 0.21-0.24
-0.5C = -0.03
C = 0.03 ÷ 0.5
= 0.06 = 6% 。
C+1.5×0.16-1.5C = 0.21
-0.5C = 0.21-0.24
-0.5C = -0.03
C = 0.03 ÷ 0.5
= 0.06 = 6% 。

1):6%+1.42×(b-6%)=20.2%
1.42×(b-6%)=20.2%-6%
(b-6%)=(20.2%-6%)/1.42
b=[(20.2%-6%)/1.42]+6%
b=0.16
2):c+1.5χ(16%-c)=21%
这里要把c看成是1χc才好解:1×c+1.5×16%-1.5×c=21%
1×c-1.5×c=21%-1.5×16%
c(1-1.5)=0.21-0.24
c=-0.03/-0.5
c=0.06
