(0.2/x+4)-(0.5/x-3)=1.4去括号和去分母

(0.2/x+4)-(0.5/x-3)=1.4去括号和去分母
(0.2/x+4)-(0.5/x-3)=1.4
去括号和去分母

(0.2/x+4)-(0.5/x-3)=1.4去括号和去分母
原方程可化为(X+4)/(1/5)-(X-3)/(1/2)=1.4
即:5(X+4)-2(X-3)=1.4
5X+20-2X+6=1.4
3X=-24.6
X= -8.2

(0.2/x+4)-(0.5/x-3)=1.4
0.2/x+4-0.5/x+3=1.4
0.2+4x-0.5+3x=1.4x
x-1.4x=0.3
-0.4x=0.3
x=-(3/4)

是0.2/(x+4)-0.5/(x-3)=1.4 ???
