(25%5x)除以2等于10解方程

5x÷2=105x=20x=4

用方程解: 5x/2=25 5x=25*2 x=10

x+5x÷2=10解:两边乘以2得:2x+5x=207x=20x=20/7

50-5X=205x=50-205x=30 x=30/5 x=6 记得采纳啊 亲

(25-5X)/20=1025-5X=10*20=2005X=25-200=-175X=-175/5=-35

(5x+2.5)除25=105x+2.5=255x=25-2.55x=22.5x=4.5

(5x-6)÷2=10.55x-6-=215x=27x=5.4

2/5x十25%X=7、80.4x+0.25x=7.80.65x=7.8x=12

(50-5x)=205x=50-205x=30 x=6

5X/2=X-10 5X=2X-20(两边同时乘以2得) 5X-2X=-20 3X=-20 X=-20/3
