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=360x=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

3x+5x=48 14x-8x=12 6*5+2x=44 20x-50=50 28+6x=88 32-22x=10 24-3x=3 10x*(5+1)=60 99x=100-x x+3=18 x-6=12 56-2x=20 4y+2=6 x+32=76 3x+6=18 16+8x=40 2x-8=8 4x-3*9=29 8x-3x=105 x-6*5=42 x+5=7 2x+3=10 12x-9x=9 6x+18=48 56x-50x

等式两边同时除以3,x=12 第二个方程把x移项到等式右边,28移项到左边,移项都要变号.X=68

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.

24x+36=40x+2解:(40-24)x=36-2 16x=34 x=2.125

4*(1+x)=361+x=36/4=9 所以,x=8 解答完毕.
