Question

(x+2)/5-(x-1)=(x+3)/3-(x-2)/2

1 (x+2)/5-(x-1)=(x+3)/3-(x-2)/2

2 (0.3x-02)/0.02-(x+1)/0.5=2

要步骤，谢谢。

Answer 1

1 (x+2)/5-(x-1)=(x+3)/3-(x-2)/2
6(x+2)-30(x-1)=10(x+3)-15(x-2)
6x+12-30x+30=10x+30-15x+30
6x-30x-10x+15x=30-12
-19x=18
x=-18/19

2 (0.3x-0.2)/0.02-(x+1)/0.5=2
15x-10-2x-2=2
13x=14
x=14/13
