40x/(50x+36)=36 解方程,在线等,谢谢谢谢,急急急急急!!!!!!!

50x+36=40x7/5 求解这个方程,要完整.解:原方程即:50x+36=5650x=56-3650x=20x=20÷50x=0.4

合并同类项,得 90x=220两边同除以90,得 x=22/9

(50x+36)/40x=7/5 5(50x+36)=280x250x+180=280x280x-250x=36030x=360 x=12

8x=0.12 3x+48=168 3x-x=156 3x+11=5x-5 3.8x=17.48 x÷6.7=19.43 3x+1.5x=135 100-5x=93 x+12.8=30 55-x=32.76 x÷70=4.9 5.6x=78.4 18x+21=48 8x-4x=56 3.6x+2.2x=63.8 2x+24=108(1)2x+8=16 (2)x/5=10 (3)x+7x=8 (4)9x-3x=6 (5)6x-8=4 (6)5x+x

x+6+x=36解:2x+6=36 2x=30 x=15

1.25x 40+40x=3650x + 40x = 3690x = 36x = 0.4希望能帮到你,如果还有不明白的地方,欢迎追问,望采纳.

把4x-6x=0减去3x-6x+2=0得到x-2=0x=2x=±√2

40x=50x(x+4)4x=5x(x+4)4x=5x+20x5x+16x=0x(5x+16)=0x=0,或5x+16=0x=0或x=-16/5.

x=8

两边都减去50,得: 50 x-50=80-50; x=30. 检验:当x=30时,方程左边=50 30=80=方程右边,所以x=30为原方程的解.
