20道一元一次方程题，别太难!也别过于简单，不需要答案，出的科学点 出的好的加分

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

Answer 2

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

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

1/3-(x-1)/2=1
(x+8)/3=-x
3-1.2x=4x/5-12
3x/4-0.4=x/2+0.3

(3x-1)/2=(4x+2)/5-1
(3x+12)/4=2-(5x-7)/3

5/3-6x=-7x/2+1
(1-x)/2-(3-3x)/4=1

x-(x-1)/2=2-(x+2)/5
x-(1-x)/3=(x+2)/6-1
(3-x)/2-(x-8)/3=1
(x-3)/2=2-(x-3)/2

(x-2)/0.2-(x+1)/0.5=3

(x+1)/0.2-(x+3)/0.01=3
(x+2)/4-(2x-3)/6=1
