用代入法(b-a)/a=x得b=ax+a为滚锋毁式1
把式1代入(b-0.95a)/0.95a=x+0.06
得(ax+a-0.95a)/0.95a=x+0.06
左边上下消a得 (x+0.05)/0.95=x+0.06
x+0.05=0.95x+0.95*0.06
0.05x=0.95*0.06-0.05
x=(0.95*0.06-0.05)/大备0.05
x=0.14
同理
(b-a)/a=x得b/a-1=x
b/a=x+1
a=b/(x+1)为基培式1
代入(b-0.95a)/0.95a=x+0.06得
( x+1){b-0.95b/(x+1)}/0.95b=x+0.06
(x+1)/0.95-1=x+0.06
x+1=0.95x+1.06*0.95
0.05x=1.06*0.95-1
x=0.14
这俩方程 无论哪个直接把已知的 A B代进去 都可以求出x啊
(B-A)÷A=X(1)
(B-0.95A)÷0.95A=X+0.06->(闷锋B-0.95A)÷0.95A-0.06=X(2)
(1)-(2)得
(蚂厅晌B-A)÷A-=(B-0.95A)÷0.95A-0.06
B/伏败A-1=B/(0.95A)-1-0.06
解得B/A=1.14
(B-A)÷A=B/A-1=0.14
用代入法(b-a)/a=x得b=ax+a为式1
