急用!50道左右!请帮忙出一些,不要应用题,只要算式和过程,还有别太简单最好有移项,合并同类项.例如：6x+2(4-x)

0.5x-0.7=6.5-1.3x
1－2（2x+3）= －3（2x+1）
2(x-2)-3(4x-1)=9(1-x)
11x+64-2x=100-9x
15-(8-5x)=7x+(4-3x)
3(x-7)-2[9-4(2-x)]=22
3/2[2/3(1/4x-1)-2]-x=2
2(x-2)+2=x+1
5x^2+3x+1=0
7x^2+x+12=0
2x^2+4x+4=0
8x^2+3x+1=0
5x^2+3x+2=0
2(x-2)-3(4x-1)=9(1-x)
11x+64-2x=100-9x
15-(8-5x)=7x+(4-3x)
3(x-7)-2[9-4(2-x)]=22
3/2[2/3(1/4x-1)-2]-x=2
2(x-2)+2=x+1
5x^2+3x+1=0
7x^2+x+12=0
2x^2+4x+4=0
8x^2+3x+1=0
5x^2+3x+2=0
45x^2+3x+100=0
89x^2+335x+1=0
x+1=3
2x+3=5
3x+5=8
4x+8=12
5x-6=9
2x-x=1
x+3=0
5x+3x=8
3x+1=2x
x-7=6x+2
5x+1=9
9x+8=24
55x+54=-1
23+58x=99
29x-66=21
0.4(x-0.2)+1.5=0.7x-0.38
x=6
30x-10(10-x)=100
x=5
4(x+2)=5(x-2)
x=18
120-4(x+5)=25
x=18.75
15x+863-65x=54
x=16.18
3(x-2)+1=x-(2x-1)
x=3/2
11x+64-2x=100-9x
x=2
x/3 -5 = (5-x)/2
2(x+1) /3=5(x+1) /6 -1
(1/5)x +1 =(2x+1)/4
(5-2)/2 - (4+x)/3 =1
x/3 -1 = (1-x)/2
(x-2)/2 - (3x-2)/4 =-1
