五年级下册解方程大全
小学五年级解方程发方法 一.移项 所谓移项就是把一个数从等号的一边移到等号的另一边去。注意,加减法移项和乘除法移项不一样, 移项规则:当把一个数从等号的一边移到另一边去的时候,要把这个数原来前面的运算符号改成和它相反的运算符号,比如“+”变成“-”,或是“×”变成“÷” 请看例题: 加减法移项: x + 4 = 9 x=9-4 x=5 乘除法移项: 3x=27 x=27÷3 x=9 常规题目, 第一步,把所有跟未知数不能直接运算的数字,转移到与未知数相反的等号那一边。 比如: 3x - 4 = 8 3x=8+4 3x=12 x=4 第二种情况请记住,当未知数前面出现“-”或是“÷”的时候,要把这两个符号变成“+”或是“×”, 具体如何改变请看下面例题: 20 – 3x=2 20=2 + 3x -----(注意:也就是前面提过的移项问题,改变符号在方程里面就是移项) 20-2=3x 18=3x x=6 36÷4x = 3 36=3×4x ----(注意:也就是前面提过的移项问题,改变符号在方程里面就是移项) 36=12x x=3 3.未知数在小括号里面的情况,注意,这种情况要分两种,第一种是根据乘法分配律先把小括号去掉 例如: 3(3x+4) = 57 9x + 12=57 9x=57-12 9x=45 x=5 第二种情况就是,要看括号前面的那个数跟等号后面的那个数是否倍数关系,如果是倍数关系,可以互相除一下,当然,用这一种方法的前提就是等号另一边的数只有一个数字,如果有多个,则先要计算成一个。 4. 第四种情况就是未知数在等号的两边都有,这种情况就是要把未知数都移项到一边,把 其它的数字移项到另一边,具体规则,如果两个未知数前面的运算符号不一样,要把未知数前面是“-”的移到“+”这一边来,如果两个未知数前面的运算符号一样,则要把小一点的未知数移到大一点的未知数那一边去。 解方程: 1)(0.5+X)+X=9.8÷2 2(X+X+0.5)=9.8 25000+X=6X 2)3200=450+5X+X X-0.8X=6 12X-8X=4.8 3)7.5×2X=15 1.2X=81.6 X+5.6=9.4 a 4)X-0.7X=3.6 91÷X =1.3 X+8.3=10.7 5)15X =3 3X-8=16 7(X-2)=2X+3 6)3X+9=27 18(X-2)=270 12X=300-4X 7)7X+5.3=7.4 3X÷5=4.8 30÷X+25=85 8)1.4×8-2X=6 6X-12.8×3=0.06 410-3X=170 9)3(X+0.5)=21 0.5X+8=43 6X-3X=18 10)1.5X+18=3X 5×3-X÷2=8 0.273÷X=0.35

五年级下册数学怎样解方程
5年级下册数学解方程解法如下: 例:98一2x=60可以把上式看成98减多少等于60(也可以把2x当作一项盖着),由数字可推出98一38=60,那么下式就可写成2x=38,从即发现2倍的x等于38,即x就等于19答案就解出来了。解:98一2x=602x=98一602x=38 x=19
