移项
0.125x+1.25x=-2.75
1.375x=-2.75
x=-2.75÷1.375
x=-2
1.375x=-2.75
x=-2
明显的X=-2
0.125x＋1.25x=-2.75
1.375x=-2.75
x=-2
0.125x+2.75=-1.25x
1.25x-2.75=0.125x 0.4x-1.6=x+2
0.125x+2.75=-1.25x x+1=1/2x-1
15X+8=2X-26,5X+8=2X-27,0.3X-1.5=X+0.6 ,0.125X+2.75=-1.25X 0.35X-1.5=-2.15X+3.5,0.125X+2.75=-1.25X ,0.35X-1.5=-2.15X+3.5
0.125乘X+2.75= -1.25X求X 帮一下了啊,谢了
（X+X)+(X-X)+(X*X)+(X/X)=100
x+1.25x=9
x*x*x*x*x=80000?
x=1+0.5x+0.25x+0.125x+0.0625x求x的值
解方程：答得好有加分 4x+3=2-x 7x+6=6x 4-3x=x+1 x+1=二分之一x-1 0.3x=1.2 0.3x-1.5=x+0.60.125x+2.75=-1.25x 0.35x-1.5=-2.15x+3.5
x*x*x=504 x*x*x=504
（x+x）+(x-x)+(x/x)=11.2
f(x)=x,x
x+x=x+15
X(X-1)=X
180=( )x( )x( )x( ) ×( )
(x+30)*(x-18)=x*x
x+ x+(x*50%)=1.5X?
