Question

0.1/0.2x-0.2-x/0.5

(x+1)/2-(2-3x)/3=1 2－(2x-4)/3 ＝－(x-7)/6 (2x＋1)/3－(5x－1)/6＝1 (0.1-0.2x)/0.03-1=(0.7-x)/0.4
( 0.3x+0.7)/0.6-(0.2x-0.4)/0.8=1

Answer 1

(x+1)/2-(2-3x)/3=1
3x+3-4+6x=6
9x=7
x=7/9
2－(2x-4)/3 ＝－(x-7)/6
12-4x+8=-x+7
3x=13
x=13/3
(2x＋1)/3－(5x－1)/6＝1
4x+2-5x+1=6
x=-3
(0.1-0.2x)/0.03-1=(0.7-x)/0.4
4-8x-1.2=2.1-3x
5x=0.7
x=0.14
( 0.3x+0.7)/0.6-(0.2x-0.4)/0.8=1
1.2x+2.8-0.6x+1.2=2.4
0.6x=-1.6
x=-8/3
