文档介绍：(人教版)(二)---去括号与去分母课时练(武邑镇中学)学校:            姓名:            班级:            考号:            评卷人得分一、-1=x-13时,去分母正确的是( )-3=2x-2             -6=2x-2             -6=2x-1             -3=2x-1             (2x-1)-2(-1+10x)=2时,去括号正确的是( )-4-2-10x=2             -4+2-20x=2             +4+2-20x=2             -4+2-20x=0             -k3-x-2k2=1的解是x=2,则k的值是( )A.-27                          C.-1311                          ,甲单独做需10天完成,乙单独做需6天完成,现由甲先做2天,,依题意可列方程( )+x6=1             +210+x-26=1             +x-26=1             +x-210+x-26=1             +14-2x+13=1时,去分母正确的是( )+1-8x-1=1             (x+1)-4(2x+1)=1             +3-8x+4=12             (x+1)-4(2x+1)=12             +2(1-x)=4的解是( )=25             =65             =2             =1             -k3-x-3k2=1的解是x=-1,则k的值是( )                          C.-1311                          (x-2)-3(4x-1)=9时的去括号的结果,其中正确的是( )-4-12x+3=9             -4-12x-3=9             -4-12x+1=9             -2-12x+1=9             ,所得结果错误的有( ) ①方程2x+13-10x+16=1,去分母,得2(2x+1)-10x-1=6 ②方程37(3x+7)=2,去分母,得21(3x+7)=14 ③方程2x-16-5x+14=1,去分母,得2(2x-1)-3(5x+1)=1 ④方程2x+32-9x+58=0,去分母,得4(2x+3)-(9x+5)=
