x%0.6x=9.46怎么解

46x9.9 =46x(10-0.1) =46x10-46x0.1 =460-4.6 =455.4

9.46-x=7.28 x=9.46-7.28 x=2.18

9.46-X=7.12 解:X=9.46-7.12 X=2.34

x+9-12=46 x-3=46 x=46+3 x=49

9.46-x=7.12 此题是一元一次方程,直接将未知数移项即可 X=9.46-7.12=2.34

46*(0.25*0.4)+9.9*46 =46*0.1+9.9*46 =46(0.1+9.9) =46*10 460

46*63

9.46-x=7.12解方程列式 解:x=9.46-7.12 x=2.34

0.62-0.32=0.3; 9.8×0.5×2=9.8; 0.25×4=1; 9.46×10=94.6; 12÷0.6=20; 13?110=730; 2.4-0.6=1.8; 0.4×0.5=0.2; 1÷0.25=4; 17+67-58=38; 9.6÷0.2=48; 0.56÷0.8=0.7; 9.13×0=0; 53.4÷10=5.34; 8.5+1.8=10.3; 0.36÷0.4=0.9; 60×0.8...

4(x-3)2=9(x+6)2,4(x-3)2-9(x+6)2=0,则[2(x-3)+3(x+6)][2(x-3)-3(x+6)]=0(5x+12)(-x-24)=0,解得:x1=-125,x2=-24.
