8x%2.4x=17.36解方程?

8x-2.4x=17.365.6x=17.36x=17.36÷5.6x=3.1

3.5X+8.5X=14412x=144x=144÷12x=1213.6-2.4X=4 两边加2.4x13.6=2.4x+4 两边减去42.4x=9.6x=9.6÷2.4x=48X(2X-7)=16 两边除以82X-7=22x=9x=4.5

8x-2.4x=5.6565.6x=5.656 x=5.656÷5.6 x=1.01 希望能够帮到你,还望采纳谢谢!

X=40

①16-8x=6.4, 16-8x+8x=6.4+8x, 16=8x+6.4, 16-6.4=8x+6.4-6.4, 8x=9.6, 8x÷8=9.6÷8, x=1.2; ②2.4x-7*5=13, 2.4x-35+35=13+35, 2.4x=48, x=20; ③1.4x÷0.8=35, 1.4x÷0.8*0.8=35*0.8, 1.4x=28, 1.4x÷1.4=28÷1.4, x=20;④3.2x+1.6x=0.48, 4.8x=0.48, 4.8x÷4.8=0.48÷4.8, x=0.1.

8x+2.4x=20.4,x=1+25/26.

先两边乘以0.6,再除以2.4即得x

8x=24x (等式两边同除以8) x=3x x-3x=0 x(x-3)=0 x1=0 ,x2=3 如果有不懂的地方可以向我追问,满意还请你采纳哦.谢谢啦!

1. 8x-16=0解: 8x=16 x=16/8 x=22. 2.4x+1.2*2=7.2解: 2.4x+2.4=7.2 2.4x=7.2-2.4 2.4X=4.8 x=4.8/2.4 x=23. 12.5x-6x=19.5解: 6.5x=19.5 x=19.5/6.5 x=3(*是乘号,/是除号)希望能帮到你 求采纳 谢谢

6.8x+2.4x=9.66 (6.8+2.4)x=9.66 9.2x=9.66 x=1.05
