X/0.7-【0.17-0.2x】/0.03等于1,起X的值?
X/0.7-【0.17-0.2x】/0.03等于1,起X的值?
X/0.7-【0.17-0.2x】/0.03等于1,起X的值?
x/0.7 - (0.17 - 0.2x)/0.03 = 1
两边同时乘以 21 得：
30x - 700(0.17 - 0.2x) = 21
30x - 119 + 140x = 21
30x + 140x = 119 + 21
170x = 140
x = 140÷170
x = 14/17
0.7/x-0.03/0.17-0.2x
(x-1)/0.3-(x+7)/0.5=1.7 x/0.7-(0.17-0.7x)/0.
解方程：x/0.7-0.17-0.2x/0.3=1
0.7/x - 0.03/0.17-0.2x =1 解方程
解方程x/0.7-0.3/0.17-0.2x=1
0.7分之x-0.03分之0.17-0.2x=1
x/0.7-1=(0.17-0.2x)/0.03
x/0.7-（0.17-0.2x）/0.03=1
x/0.7-0.17-0.2x/0.03=1
x/0.7-0.17-0.2x/0.03=1
x/0.7—0.17—0.2x/0.13=1
x/0.7-(0.17-0.2x)/0.13=1
X/0.7-（0.17-0.2x）/0.03=1
X/0.7-0.17-0.2x/0.03=1
解方程:0.4(x-0.2)+1.5=0.7x-0.
解方程：x/0.7-0.17-0.2x/0.03=1(2)2x+1/6+x-1/3=1
X分之0.7-0.17-0..2X分之0.03等于一,求X的值
X/0.7-【0.17-0.2x】/0.03等于1,起X的值?
