100(95-x) - 80(100-x) = 100 (240-x)/x*100%=20% (100%-10%)*y=
(X+X)+(X-X)+(X*X)+(X/X)=100
X+Y=7(100X+Y)-(10Y+X)=(10Y+X)-(10X+Y)
X+X+X+X+X+X+100X=1690 问:X等于多少
If two even number x,y satisfy equation x×x+100=y×y,x
y=[100-(x-20)*10]*(x-18)计算过程
解方程.100/(X+Y)+64/(X-Y)=9;80/(X+Y)+80/(X-Y)=9
解方程 x+x/3=100 x+3x=100 100-x=x*3 x=(100-x)*3 x+y=100
【(2x+y)²-y(y+4x)-8x】÷2x,其中x=100
x=91;y=100; while(y>0){ @ if(x>100){x-=10;y--;} else x++;}
2x+3x+4x+5x+x+6x+7x=100
(x+x)+(x-x)+(xx)+(x/x)=100 求x的值?用方程解
matlab画图x = 0:0.01:10; y =sin(2*x)*cos(100*x)/(2*x); plot(x,
