问题描述:

解方程 (X+4÷80%*0.2)÷(X+48÷0.8)=36%

(X+4/0.8*0.2)/ (X+48/0.8) =0.36
( X+5*0.2) / (X+60) =0.36
( X+1) / (X+60)=0.36
X+1=0.36(X+60)
X-0.36X =21.6-1
0.64X=20.6
X=515/16

(X+4÷80%*0.2)÷(X+48÷0.8)=36%
(X+1)÷(X+60)=0.36
两边乘以X+60
X+1=0.36(X+60)
X+1=0.36X+21.6
X-0.36X=21.6-1
0.64X=20.6
X=20.6/0.64
X=32.1875

(X+4÷80%*0.2)÷(X+48÷0.8)=36%
(x+1)÷(x+60)=0.36
x+1=0.36*(x+60)
x+1=0.36x+21.6
x-0.36x=21.6-1
0.64x=20.6
x=32.1875
