8x+80×0.03=75×0.75
8x+80×0.03=75×0.75
8x+80×0.03=75×0.75
8x+80×0.03=75×0.75
8x=75×0.75-80×0.03
8x=56.25-2.4
8x=53.85
x=6.73125
X＝6.73125
8x+2.4=56.25 x=（56.25-2.4）/8
8x+80×0.03=75×0.75
125x(80+8)=( )x( )+( )x( )
解方程4x+3.6﹦8x－4.8 75(x-0.75)=60x
1-75%X=0.75 求x?
(x+75)/(4x-75)=8:
80-8x+8x=16+8x
x/80+x/75=9.3
4（x+5）+8x=80x=?
解x-2/5x+8=80%x-4
x-1/4x+8=80%x
5(8+x)+3x=80求未知数x
8x+2x+10x=80
(X/2*75%）+8=X
1/4x+8=80%x
4(x+5)+8x=80
解方程 x+4/11x=75 x-1/4x=120 3x+12x=180 8x-x=175
0.75x-1/2x=-5;3x+5=4x+1;3X+5=4X+18;1-7x=x-7;9x+8-7x=3x;-(x-2)=3(1-x);3x-7(x-1)=3-2(x+3)解方程详...0.75x-1/2x=-5;3x+5=4x+1;3X+5=4X+18;1-7x=x-7;9x+8-7x=3x;-(x-2)=3(1-x);3x-7(x-1)=3-2(x+3)解方程详细一点
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
