求初中一年级数学解方程计算题10题 谢谢

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

追问

最好是把每题分解清楚
