6x+8x=1.4x3解方程

6x+8x=1.4*3 14x=4.2 x=4.2/14 x=0.3

6x+8x=1.4x314x =4.2 x=4.2÷14 x=0.3

1/6x=3/8x.解方程.1/6x=3/8x 解:十字相乘,得8x=18x x=9/4

2*(7x-4x) =186x=18 x=36x+8x=1.4*314x=4.2 x=0.3

6x+8x=4.2 14x=4.2 x=0.3

12x=3+4.2 12x=7.2 x=0.6

2x=4,x=2.

(1)8x+7*3=61, 8x+21-21=61-21, 8x÷8=40÷8, &n

8x-5=6x+3x=8/2=4如有帮助请采纳,如对本题有疑问可追问,Good luck!

6x+8x3=360(6+24)x=360x=3603012=x
