小学数学五年级解方程练习题及答案解方程练习题一:1. 解方程:3x + 5 = 202. 解方程:4(x + 3) = 323. 解方程:2(2x - 1) = 6x + 44. 解方程:5 - 2x = 95. 解方程:3(x + 3) - 2(2x - 1) = 5x - 6解方程练习题二:1. 解方程:2x + 3 = 7x - 42. 解方程:5(3x - 2) = 163. 解方程:4(x + 2) - 3(x - 1) = 2(x + 5)4. 解方程:3(2x - 1) = 2(x + 4)5. 解方程:2(x - 1) + 3(4x + 5) = 20解方程练习题三:1. 解方程:3x + 4 = 7x + 92. 解方程:2(x + 3) = 3(x - 2)3. 解方程:5(2x - 3) - 4(3x - 2) = 5 - 6x4. 解方程:4(3x + 5) - 2(2x - 1) = 3(2x + 7)5. 解方程:2(3x - 4) = 3(2x + 5) - 4(1 - x)解方程练习题四:1. 解方程:5x + 2 = 3x - 62. 解方程:4(x + 1) = 2(2x - 3)3. 解方程:3(2x - 1) - 2(x + 4) = 54. 解方程:2(3 - x) = 3(2x + 1) - 2(x - 6)5. 解方程:4(3x + 2) = 2(x + 5) - 3(2 - x)解方程练习题五:1. 解方程:2x - 3 = 3(x + 4)2. 解方程:4(2x - 1) - 5x = 2(3 - x) - 13. 解方程:3(4 - 2x) - 4(1 + x) = 74. 解方程:5(2x + 1) - 3(x - 2) = 65. 解方程:3(3x + 2) = 2(4 - x) - 3(2x - 1)解答:解方程练习题一:1. 解方程:3x + 5 = 20解:首先将常数项移到等号的另一边,得到3x = 20 - 5,化简得到3x = 15,再将系数3移到等号的另一边,得到x = 15 / 3,最终计算得到x = 5。

五年级数学解方程计算题100道一、简单的一步方程(1 - 10题)1. x+5 = 12- 解析:这是一个简单的加法方程,根据等式的性质,等式两边同时减去一个相同的数,等式仍然成立。
为了求出x的值,我们在方程两边同时减去5,得到x = 12 - 5,解得x=7。
2. x - 3=8- 解析:这是减法方程,根据等式性质,等式两边同时加上3,即x=8 + 3,解得x = 11。
3. 3x=15- 解析:这是乘法方程,等式两边同时除以3,x=(15)/(3),解得x = 5。
4. xdiv4 = 6- 解析:这是除法方程,根据等式性质,等式两边同时乘以4,得到x=6×4,解得x = 24。
5. 2x+3 = 7- 解析:首先把2x看成一个整体,方程两边同时减去3,得到2x=7 - 3,即2x = 4,然后再等式两边同时除以2,解得x = 2。
6. 3x - 5=10- 解析:先把3x看成一个整体,方程两边同时加上5,得到3x=10 + 5,即3x = 15,再等式两边同时除以3,解得x = 5。
7. 5xdiv2 = 10- 解析:先根据等式性质,方程两边同时乘以2,得到5x=10×2,即5x = 20,然后等式两边同时除以5,解得x = 4。
8. x+7 - 9 = 5- 解析:先化简方程左边x+7 - 9=x - 2,则方程变为x - 2 = 5,方程两边同时加上2,解得x = 7。
9. 3(x + 2)=18- 解析:先把括号展开,得到3x+6 = 18,把3x看成一个整体,方程两边同时减去6,得到3x=18 - 6,即3x = 12,再等式两边同时除以3,解得x = 4。
10. 2(x - 3)+5 = 7- 解析:先把括号展开2x-6 + 5 = 7,化简得2x - 1 = 7,方程两边同时加上1,得到2x=7 + 1,即2x = 8,再等式两边同时除以2,解得x = 4。
小学五年级数学解方程练习题及答案解方程练习题:1. 将一个数的5倍加上8,得到的结果等于21。
请你用代数方法求出这个数是多少。
2. 若一个数的3倍再加上4等于16,那么这个数是多少?3. 某个数的2倍减去3等于13。

请你计算出这个数。
7. 若一个数加上9后再除以3得到的商等于6,那么这个数是多少?8. 某个数的3倍减去2等于10,那么这个数是多少?9. 将一个数的4倍减去5,得到的结果等于27。
请你计算出这个数。
10. 若一个数的7倍加上3等于38,那么这个数是多少?解方程题答案:1. 设这个数为x,则根据题意得到方程: 5x+8=21。
解方程得到:x=13/5。
2. 设这个数为x,则根据题意得到方程: 3x+4=16。
解方程得到:x=12/3=4。
3. 设这个数为x,则根据题意得到方程: 2x-3=13。
解方程得到:x=(13+3)/2=8。
4. 设这个数为x,则根据题意得到方程: 2x+6=18。
解方程得到:x=(18-6)/2=6。
5. 设这个数为x,则根据题意得到方程: x/3+4=8。
解方程得到:x=(8-4)*3=12。
6. 设这个数为x,则根据题意得到方程: (x-5)*2=16。
解方程得到:x=(16/2)+5=13。
7. 设这个数为x,则根据题意得到方程: (x+9)/3=6。
解方程得到:x=(6*3)-9=9。
8. 设这个数为x,则根据题意得到方程: 3x-2=10。
解方程得到:x=(10+2)/3=4。
9. 设这个数为x,则根据题意得到方程: 4x-5=27。
解方程得到:x=(27+5)/4=8。
10. 设这个数为x,则根据题意得到方程: 7x+3=38。
解方程得到:x=(38-3)/7=5。
