解方程.6x÷5=9.6 1.7x+

(1)6x÷5=9.6, 6x÷5*5=9.6*5, 6x÷6=48÷6,x=8; (2)1.7x+0.4x=3.15, 2.1x=3.15, 2.1x÷2.1=3.15÷2.1, x=1.5;(3)5x-2*0.8=33.4,5x-1.6+1.6=33.4+1.6, 5x=35, 5x÷5=35÷5, x=7;(4)3(x-2.4)=8.4,3(x-2.4)÷3=8.4÷3, x-2.4=2.8, x-2.4+2.4=2.8+2.4, x=5.2.

解:6X÷5=6 方程两边同时乘以5得6x=30 一次项系数化为一得 x=5 有不明白的地方再问哟,祝你学习进步,更上一层楼! (*^__^*)

计算:8x -6x=9.62x=9.6 x=4.8 验算:把x=4.8代入原式,得:8*4.8-6*4.8=38.4-28.8=9.6 与原式相等

1.2*4等于4.8,然后用9.6减去4.8等于4.8.最后用4.8除于6等于0.8.答案就是0.8.采纳我哦,手机打字很辛苦呀!希望采纳

3.6x+4.8x=2.18.4x=2.1x=2.1÷8.4x=0.25

6x+1.2* 4=9.6 6x=9.6-4.8 x=4.8÷6 x=0.8

(6X+5)÷2=15.16x+5=30.26x=25.2x=4.2

(X6+9.6)÷4=6解:6X+9.6=246X=24+9.6=33.6 X=5.6 3.8x10.1=3.8x(10+0.1)=3.8x10+3.8x0.1=38+0.38=38.38

(9+6)x=1.515x=1.515x÷15=1.5÷15x=0.1满意请采纳

6x/5=126x=12*5=60x=60/6=10
