x-0.64x=17.28怎么解
x-0.64x=17.28怎么解

x-0.64x=17.28怎么解
17.28=(1-0.64)x=0.36x x=17.28/0.36=48

（1-0.64）X=17.28，故X=17.28/0.36=48

x-0.64x=17.28
0.36x=17.28
x=17.28/0.36
x=48

x-0.64x=17.28怎么解 x*x-x=90怎么解 5.6x=17.28-4x这个方程怎么解?5.6x=17.28-4x x^2=(x+30)X(x-18)怎么解 x 5x=21.6-x-5x怎么解 (x+12)*(x+12)=x*x+360怎么解 x-(30-x)=(30-x)-x/3,怎么解 x*x=(x+10)*(x-6)怎么解 x(x+x)=48 求x 怎么解 (x+x+23+x+50)=3x 怎么解 x*x=75%x*(x+3)怎么解? (168+X)/(288+X)=(120-X)/X怎么解 x*x+2*x+1=36,x怎么解, x(x+1)-x(x-1)=188怎么解, 25%X+(144-x)=x-25%X怎么解 x(x+1)-x(x-1)=188怎么解, (x+3)*(x+3)-x*x=81怎么解 x(x+5)+(x+5)x=121怎么解
