解
2x-(1+3x)=2(x-2)
2x-1-3x=2x-4
-3x=-3
x=1
3+(4x-2)=6
3+4x-2=6
4x=5
x=5/4y-2分之y-1=2-2分之y+2描述清楚,哪里该加括号,还是发图片也行y-(y-1/)/2=2-(y+2)/2这个吗y-2分之(y-1)=2-2分之(y+2)=?y-(y-1)/2=2-(y+2)/2两边乘以2得:2y-(y-1)=4-(y+2)2y-y+1=4-y-2y+1=2-y2y=1y=1/2最后一题3分之(2x-2)-2分之(x-1)=x-2解两边乘以6得:2(2x-2)-3(x-1)=6(x-2)4x-4-3x+3=6x-12x-1=6x-125x=11x=11/5
