100+(X-100)/10=200+[X-200-100-(X-100)/10]/10
100+(X-100)/10=200+[X-200-100-(X-100)/10]/10
(X+X)+(X-X)+(X*X)+(X/X)=100
已知x=100,求x(x+1)分之1+(x+1)(x+2)分之1+(x+2)(x+3)分之1+.+(x+99)(x+10
(100x+100)(x+10%)=56
(x-10)^2+(√2x-x)^2=100
[100(2X + 1) + 10X + 2X + 2] + [100(2X + 2) + 10(2X + 1) + X
(x-10)/x*100%=50%求解
5x+27=30+0.5x 100-4(8-3x)=200 3.5x-1.2=2.7x+3 7(x
帮我解几道方程、、8x-4(10-x)=44 60x+(100-x)*65=100*63 30x-20(180-x)=5
200+10x=150+20x
2(200-x)-4x=100 怎么解
方程(X-10)(X-1)=100的解
