0.7-0.1x/0.6-0.01x-0.01/0.04=x+1
0.7-0.1x/0.6-0.01x-0.01/0.04=x+1
0.7-0.1x/0.6-0.01x-0.01/0.04=x+1
0.7-0.1x/0.6-0.01x-0.01/0.04=x+1,
即0.7-x/6-0.01x-1/4=x+1,
两边都乘以12,得
8.4-2x-0.12x-3=12x+12,
8.4-3-12=12x+2x+0.12x,
即 14.12x= -6.6,
x= -165/353.
0.7-0.1x/0.6-0.01x-0.01/0.04=x+1
0.7-x/6 -0.01x-1/4 =x+1
4.2-x-0.06x-1.5=6x+6
6x+x+0.06x=4.2-1.5-6
7.06x=-3.3
x=-3.3/7.06
x=-0.467
