x÷0.8=25.6解方程

x÷0.8=25.6 x=25.6X0.8 x= 20.48

8.6x=25.8×0.6 8.6x=15.48 x=1.8

x=16/25x5/6 x=8/15

25.6+x=70 x=70-25.6 x=44.4 ----------------------------------------------------------

6%x÷25分之6=4分之5 0.06x/(6/25) = 5/4 0.25x=5/4 x=5

x/2 + 6.25=2x 6.25=1.5x x约=4.17

6(x+2)一4.8=25.8 6(x+2)=30.6 x+2=5.1 x=3.1

36(x+27)=45(x-25) 解:36x+972=45x-1125 45x-36x=972+1125 9x=2097 x=2097÷9 x=233 6(x-2)=5(8-x)-8 解:6x-12=40-5x-8 6x+5x=40-8+12 11x=44 x=44÷11 x=4

x÷6/35=26/45÷13/25 35x/6=26/45 *25/1335x/6=10/935x=(10*6)/9x=4/21

0.4x=18.6-16.25 0.4x=2.35 x=5.875
