0.1x/0.2%0.01x%0.01/0.06=x%1/3怎么算

0.1x/0.2-0.01x-0.01/0.06=x-1/3 0.1/0.2x-0.01x-1/6=

原式即:x/2 -x/100 - 1/6 =x -1/3 x - 50x/100

解: (1) (0.1x-0.2)/0.01-(x+1)/0.5=2 去分母得 (10x-20)-2

x+1/0.2-x+3/0.01=3 5x+5-100x-300=3; 95x=-298; x

看不清,是 ( 0.1/0.2 ) x - ( 0.01/0.06 ) x - 0.02 = x ×

0.1x+0.3/0.2+2.5=0.4x-1/0.5 方程两边乘以10 x+15+25=

如下

0.5x-1/0.2-0.1x+2/0.3=1 两边乘0.6 3(0.5x-1)-2(0.1x+2

8X-(5-X)=10X+2 7X-5=10X+2 3X=-7 X=-7/3

两边乘1.2 0.1x-0.4=4(0.2x+1) 0.1x-0.4=0.8x+4 移项 0
