1.7-2x/0.3=x/0.7-1 解方程
解方程x/0.7-(1.7-2x)/0.3=1
0.3分之(1.7-2x)=0.7分之(x)-1
0.7分之x-0.3分之1.7-2x=1
0.3分之1.7-2x=0.7分之x-1
x/0.7-1.7-2x/0.3=1
x/0.7-(1.7-2x)/0.3=1
1.7-2x/0.3=x/0.7-1
求解x/0.7-1.7-2x/0.3=1
(x-1)/0.3-(x+7)/0.5=1.7 x/0.7-(0.17-0.7x)/0.
(1.7-2x)/0.3=x/0.7-1,(3+0.2x)/0.2-(0.2+0.03x)/0.01=0.75
1/2x-1/4(x-1)=2/3(x-1)x - x-1 / 3 = 1 - x+3 / 5x / 0.7 - 1.7-x / 0.3 = 1
