六年级解方程练习题3 姓名 成绩 一、简单的类型 x－ EQ \F(2,7) x= 2x + EQ \F(3,5) 70%x+ 20%x = 3.6 x× EQ \F(2,5) = =20× 25% + 10x = x - 15%x = 68 x＋ x＝121 5x－3× ＝ x÷ ＝12 6x＋5 =13.4 x + x = 4 4x－3 ×9 = 29 x＋ x= 4x－6× =2 3,10) EQ \F(12,5) ÷x = x = × x÷ = × 2、 式子一边有很多运算的方程 对于这类方程我们应该先根据运算律，把能够计算出来的先计算出来 3、 有括号的方程 对于有括号的题，我们一般来说先去掉括号，然后按上面的方法进行计算 4、 运用乘法分配律的方程 先运用乘法分配律，然后去括号。 5、 左右两边都有x的方程 根据等式的性质，把方程一边的x消掉，然后根据上面讲过的步骤进行 6、 综合运用 - 1 - _1234567921.unknown _1234567937.unknown _1234567945.unknown _1234567953.unknown _1234567957.unknown _1234567959.unknown _1234567961.unknown _1234567962.unknown _1234567960.unknown _1234567958.unknown _1234567955.unknown _1234567956.unknown _1234567954.unknown _1234567949.unknown _1234567951.unknown _1234567952.unknown _1234567950.unknown _1234567947.unknown _1234567948.unknown _1234567946.unknown _1234567941.unknown _1234567943.unknown _1234567944.unknown _1234567942.unknown _1234567939.unknown _1234567940.unknown _1234567938.unknown _1234567929.unknown _1234567933.unknown _1234567935.unknown _1234567936.unknown _1234567934.unknown _1234567931.unknown _1234567932.unknown _1234567930.unknown _1234567925.unknown _1234567927.unknown _1234567928.unknown _1234567926.unknown _1234567923.unknown _1234567924.unknown _1234567922.unknown _1234567905.unknown _1234567913.unknown _1234567917.unknown _1234567919.unknown _1234567920.unknown _1234567918.unknown _1234567915.unknown _1234567916.unknown _1234567914.unknown _1234567909.unknown _1234567911.unknown _1234567912.unknown _1234567910.unknown _1234567907.unknown _1234567908.unknown _1234567906.unknown _1234567897.unknown _1234567901.unknown _1234567903.unknown _1234567904.unknown _1234567902.unknown _1234567899.unknown _1234567900.unknown _1234567898.unknown _1234567893.unknown _1234567895.unknown _1234567896.unknown _1234567894.unknown _1234567891.unknown _1234567892.unknown _1234567890.unknown
