X-X×0.2=1.18X-X×0.2=1.18X-X×0.2=1.18当然能算出来X-X×0.2=1.18（1-0.2）X=1.180.8X=1.18解得X=1.475

X-X×0.2=1.18
X-X×0.2=1.18

X-X×0.2=1.18
当然能算出来
X-X×0.2=1.18
（1-0.2）X=1.18
0.8X=1.18
解得X=1.475

X-X×0.2=1.18 （X+X)+(X-X)+(X*X)+(X/X)=100 x-30-0.2x=0.5x x-0.2x=80 求x (X-8)/X=0.2(X-8)/X=0.2 (x-1)+(x+2)+0.2x+2x=46 x-0.2.x=180 x-0.2x=36 x=120+(x ×0.2) x*x*x*x*x=80000? 0.2x+0.4x=12 x=?20x+x=420 x=? x*x*x=504 x*x*x=504 （x+x）+(x-x)+(x/x)=11.2 1.18-2（3-4X)=10X2.X/2-X=(X+5)-2X f(x)=x,x x+x=x+15 X(X-1)=X 180=( )x( )x( )x( ) ×( )
