100道一元一次方程计算题

100道一元一次方程计算题一、基础巩固篇（25题）这一部分主要考察最基本的一元一次方程形式，包括简单的移项、合并同类项等操作，是后续学习的基石。1.x+5=122.8-y=33.3a=214.m/4=55.2x+7=156.5y-3=127.10-3b=18.4c/3=89.6x-8=4x10.7y+5=3y+1711.9a-12=5a+412.13-2m=5m+613.3(x+2)=1514.4(2y-1)=1215.5-2(x-1)=316.3(1-a)+2a=417.(x/2)+3=718.(y/3)-2=119.5-(m/4)=220.(2n/5)+1=321.3x+4x=2122.8y-5y-2y=923.6a-(3a+2)=1024.12-(5b-7)=425.(x+4)/3=6二、去括号专项篇（25题）去括号是解一元一次方程中容易出错的环节，特别是括号前是负号或系数时。本部分集中训练去括号法则的应用。26.2(x+3)+5=1927.3(2y-1)-2=1028.4(1-a)+3(a+2)=129.5(m-3)-2(2m+1)=430.6-(x-2)=3(x+1)31.7-2(y+3)=3(y-1)32.3(2a+5)=2(a+4)+133.4(3b-1)-5(2b+3)=-1134.(x-1)+2(x+2)=835.2(y+5)-3(y-1)=1236.5(1-m)-3(2-m)=437.3(2n+1)=4(n-3)+1538.6-3(x+1)=2(2-x)39.2(4y-3)+5(1-y)=3y+140.(a+2)-3(2a-1)=1-4a41.3[x+2(x-1)]=1842.2[3(y-1)+4]=2043.5-[2(m+3)-4]=144.4-2[3(n-1)+6]=-245.2(x-1)-(x+2)=3(1+x)46.3(2y+1)-2(y-2)=5(y+3)47.(a-3)+2(3a-1)=4(a+1)-548.5(2m-1)-3(3m+2)=4(m-3)+149.2[x-(x-1)]=3(x-1)50.3{2[y-(y+1)]}=4(y-2)三、去分母深化篇（25题）当方程中含有分母时，去分母是首要步骤。此部分着重练习如何正确找到最简公分母、去分母以及避免漏乘等问题。51.(x/2)+(x/3)=552.(y/4)-(y/5)=153.(2a/3)+1=(a/2)+354.(3b/5)-2=(b/2)-155.(x-1)/2=(x+2)/356.(y+3)/4=(2y-1)/557.(2a-1)/3-(a+1)/4=158.(3b+2)/5+(b-1)/2=259.x-(x/3)=660.1-(y/2)=(y/3)+261.(m/2)+(m/3)+(m/6)=662.(2n-1)/5-1=(n+1)/263.(x+1)/2-1=(2x-1)/364.(3y-2)/4+(y+3)/5=y-165.1-(a-2)/3=(a+3)/466.(5b+1)/6-(b-2)/3=(2b+1)/467.(x/2)-(x-1)/3=168.(2y+1)/3+(y-1)/4=(3y+5)/1269.(3a-2)/5-(a+6)/10=1-(a/2)70.(4m+3)/6+(m-2)/3=(5m-4)/971.(x+2)/5=1-(2x-1)/372.(y-3)/2-(4y+1)/5=173.1-(a+1)/6=(2a-5)/4+a74.(3b-1)/7-(5b+1)/4=-175.(2x-1)/3-(x+2)/6=(4x-3)/5-1四、综合提升篇（25题）本部分题目综合性较强，可能需要同时运用去括号、去分母、移项、合并同类项等多种技巧，部分题目还需要先进行简单的整理。76.5x-3(2x-1)=7-(3x+2)77.4(y+1)-3(2y-5)=12-(y-2)78.(a/3)+2(a-1)=(a+3)/2+179.2(m-1)/3-(m+2)/4=(3m-5)/680.3[x-2(x-1)]=2(1-x)+581.5{2[y-(y-1)]+3(y+1)}=1082.(x+1)/3-(x-2)/5=(2x-1)/15+183.2(y-1)/4+(y+2)/3=(3y-1)/6-1/284.0.5a+0.3(a-1)=0.4a+0.285.0.2(3b+1)-0.5(b-2)=0.1(5b-4)86.1-(x-2)/4=(2x-1)/3-(x+1)/687.3(2m-1)/4-(m+2)/5=(m-3)/2+1/1088.2[3(x-1)+4]-5=6[(x+1)/2-1]89.(y+3)/2-1=(2y-1)/3-(y-2)/690.5(a-1)/6-(a+2)/3=(3a-4)/4-(a+1)/291.3(x+2)-2[4x-3(x-1)]=x+1892.4(2y-1)/3-(y+2)/2=(5y-2)/6-(y-8)/493.(m-1)/2+2(m+1)/3=(m-3)/4-(m+4)/5+294.2{3[4(n-1)-(n+2)]+5}=3n+195.(2x-3)/5-(x-4)/3=(x+2)/15-(x-1)/2096.3(y+1)/0.2-(y-1)/0.5=1(提示：可先化为整数系数方程)97.(a-0.5)/0.3+(2a+1)/0.2=10(提示：可先化为整数系数方程)98.1/2(x-1)-1/3(x+2)=1/4(x-3)+199.3/4(m+2)-2/3(2m-1)=1/2(m-5)-1/6100.2[(x+1)/3-(x-1)/4
