Question

50道带括号的方程,帮一下（一元一次）

Answer 1

2(x-1)-3(x+1)=1 3(x-1)-4(x+1)=1 4(x-1)-5(x+1)=1 5(x-1)-6(x+1)=1 6(x-1)-7(x+1)=1
7(x-1)-3(x+1)=1 8(x-1)-3(x+1)=1 2(x-1)-9(x+1)=1 2(x-1)-3(x+1)=2 2(x-1)-3(x+1)=3
2(x-1)-4(x+1)=4 2(x-2)-3(x+1)=2 2(x-3)-3(x+2)=5 2(x-1)-5(x+1)=1 7(x-1)-3(x+2)=1
2(x-1)-1=3(x+1) 1-2(x-1)=3(x+1) 2(x-1)=3(x+1)+1 2(x-1)=3(x+1)-3 2(x-1)-3=1-(x+1)
1/2(x-1)-1/3(x+1)=1 2(x-1)-3(x+1)=1/2 2(x-1/2)-3(x+1/3)=1 2(1/2x-1)-3(1/3x+1)=1 1/2(2x-1)-1/3(3x+1)=1
练吧,求出后代人检验,实在不好解的,就去掉行了.
