计算0.02x-0.01/0.03-x+0.1/0.6=0.2x+0.1/0.4-1

0.2x+1/0.1-0.05-0.4x/0.02=1 求x的解,要具体计算过程 解方程:2- x+5/6=x- x-1/3,0.1-0.2x/0.03-1=0.7-x/0.4 计算:(4x-1.5)/0.5-(5x-0.8)/0.2=(1.2-x)/0.1 解方程0.3x+0.2/0.4-0.05x+0.01/0.02=0.7x-0.1/0.3 0.1x+0.2x+0.5（38-2x）=9.2 求计算过程!要清楚,快!1 计算1/[x(x+3)]+1/[(x+3)(x+6)]+.+1/[(x+15)(x+18)]=? 已知y=x²-x,计算x=2处当△x分别等于1,0.1,0.01时的△y及dy 设函数y=x^2+x,计算在x=2处当△x分别等于1,0.1,0.01时的△y及dy. x/0.1-(x-1)/0.2=10 1-0.3分之1.7-2x＝0.7分之x-1 0.3分之0.2x-0.1-0.05分之0.01x+0.02=0.1x 2- 6分之x+5=x- 3分之x-1 ,0.03分之0.1-0.2x-1=0.4分之0.7-x 怎么解方程!急 6000+（X-3500)*0.1-105=X,求计算步骤.
