解答
2分之3x-1+3分之5x+2=2-6分之4x-2
3x/2-1+5x/3+2=2-4x/6-2
3x/2+5x/3+1=-4x/6
9x+10x+6=-4x
19x+4x=-6
23x=-6
x=-6/23
推荐
1.1-4x/0.6-1.3-3x/0.2=5x-0.4/0.3
已知6(x+1)-4x>3(5x+2)+5,化简:|3x+1|-|1-3x|.
3(x-3)=5-2(2-5x); 2(4x-3)-5=6(3x-2)-2(x+1)
(3x-1/2)+(5x+2/3)=2-(4x-2/6)
0.6分之1.1-4x-0.2分之1.3-3x=0.3分之5x-0.4
两数和为3,积为-10 求这两个数
