解方程: (x+1)/0.2-(0.1x-0.2)/0.03=0.5
(x+1)/0.2-(0.1x-0.2)/0.03=0.5
去括号后化简 (5 x+35)/3 = 0.5
x = - 67/10 = - 6.7
再问: 要有具体过程,谢谢了啊
再答: (x+1)/0.2-(0.1x-0.2)/0.03 = 0.5 (10x+10)/2 -(10x-20)/3 = 0.5 5x + 5 - 10/3 x + 20/3 = 0.5 (5 x+35)/3 = 0.5 x = - 67/10 = - 6.7
去括号后化简 (5 x+35)/3 = 0.5
x = - 67/10 = - 6.7
再问: 要有具体过程,谢谢了啊
再答: (x+1)/0.2-(0.1x-0.2)/0.03 = 0.5 (10x+10)/2 -(10x-20)/3 = 0.5 5x + 5 - 10/3 x + 20/3 = 0.5 (5 x+35)/3 = 0.5 x = - 67/10 = - 6.7
解方程:2- x+5/6=x- x-1/3,0.1-0.2x/0.03-1=0.7-x/0.4
解方程:x/0.7-0.17-0.2x/0.03=1
0.7/x - 0.03/0.17-0.2x =1 解方程
解方程-0.4x+0.1=-0.5x+0.2
(1)1-x/3=8-2x/2[解方程][过程要有] (2)0.1x-0.2/0.02=3+x+1/0.5[解方程][过
解方程:x-0.2x = 18
解方程解方程0.5分之x-3-0.2分之x+4=1
解方程:2-0.1X+0.2/0.5=X-0.01X-0.01/0.02 急啊~~~ 快
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
0.1x/0.03-(0.9-0.2x)/0.7=1 解方程
解方程,0.1分之1+x-0.2分之0.4x-0.5=1分之2
解方程(1+x)/0.1-(0.4x-0.5)/0.2=1/2
