求方程带括号两边都有未知数的例题40道

40道，带括号一个，两边都有X的方程

Answer 1

7(2x-1)-3(4x-1)=4(3x+2)-1;

(5y+1)+(1-y)=(9y+1)+(1-3y);

20%+(1-20%)(320-x)=320×40%

2(x-2)+2=x+1

2(x-2)-3(4x-1)=9(1-x)

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

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)-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

1.7(2x-1)-3(4x-1)=4(3x+2)-1
2.(5y+1)+(1-y)=(9y+1)+(1-3y)
3.[(-2)-4]=x+2
4.20%+(1-20%)(320-x)=320×40%
5.2(x-2)+2=x+1
6.2(x-2)-3(4x-1)=9(1-x)
7.11x+64-2x=100-9x
8.15-(8-5x)=7x+(4-3x)
9.3(x-7)-2[9-4(2-x)]=22
10.3/2[2/3(1/4x-1)-2]-x=2
11.5x+1-2x=3x-2
12.3y-4=2y+1
13.87X*13=5
14.7Z/93=41
15.15X+863-65X=54
16.58Y*55=27489
17.2（x+2）+4=9
18.2(x+4)=10
19.3(x-5)=18
20.4x+8=2(x-1)
21.3(x+3)=9+x
22.6(x/2+1)=12
23.9(x+6)=63
24.2+x=2(x-1/2)
25.8x+3(1-x)=-2
26.7+x-2(x-1)=1
27.x/3-5=(5-x)/2
28.2(x+1)/3=5(x+1)/6-1
29.(1/5)x+1=(2x+1)/4
30.(5-2)/2-(4+x)/3=1
