解方程3/2|x+5|=5
解方程(1)4x-2=3-x
(2)-x(x-2)=12
(3)32x+1/3=x+2/4-1
(4)x-1/2=2-x+2/5
(5)3/2[2/3(x/4-1)-2]-x=2
解方程(1)4x-2=3-x
(2)-x(x-2)=12
(3)32x+1/3=x+2/4-1
(4)x-1/2=2-x+2/5
(5)3/2[2/3(x/4-1)-2]-x=2
4x-2=3-x 4x+x=3+2 5x=5 x=1
-x(x-2)=12 x²-2x+12=0 无实数解
32x+1/3=x+2/4-1 31x=-5/6 x=-5/186
x-1/2=2-x+2/5 2x=29/10 x=29/20
3/2[2/3(x/4-1)-2]-x=2 x/4-1-3-x=2 -3x/4=6 x=-8
-x(x-2)=12 x²-2x+12=0 无实数解
32x+1/3=x+2/4-1 31x=-5/6 x=-5/186
x-1/2=2-x+2/5 2x=29/10 x=29/20
3/2[2/3(x/4-1)-2]-x=2 x/4-1-3-x=2 -3x/4=6 x=-8
