20.8-(x-1.5)=1.25
20.8-(x-1.5)=1.25
20.8-(x-1.5)=1.25
20.8-(x-1.5)=1.25
20.8-x+1.5=1.25
20.8+1.5-1.25=x
x=19.55
20.8-(x-1.5)=1.25
x+ x+(x*50%)=1.5X?
0.5x-1.5=-1.25x
x-0.48x=20.8
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
1.5x=x-1.6＊x
x+(x-1.4)+1.5x=33.
30/x=30/(x-1.5)-x
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
x+1.25x=9
X/1.5-1.25=0.75
x-1.5x=56
6.5x+x=1.5
x+12=1.5x
1.5x+x=12.
X+1.5%X=7.5
X+1.5X=35
