x=1.5x-30
30/x=30/(x-1.5)-x
x=1.5x-30
x+ x+(x*50%)=1.5X?
(x+30)*(x-18)=x*x
(25-30)*1.5%x+x=1323 x=?
17.16-x=4x+1.5
1.5x+27=30+0.5x
1.5x+27=30+0.5x
X+1.5X=30怎么算?
30x=40(x-2)
(X+X)+(X-X)+(X*X)+(X/X)=100
1.5x=x-1.6*x
x+(x-1.4)+1.5x=33.
0.8x=x-30 x=
x ( x-30)= -67.5 X=?
30X-2X=84 5.8X-X=60 6.6X-5X=8 4X-X=24 1.5X-X=1要写过程求X值
x-30-0.2x=0.5x
3X+30+X+X-15=?
