X=1.5
0.75x+0.5x=2.25
x÷0.5-2.25=0.75
X÷0.5-2.25=0.75,这个方程怎么解
0.5x=0.75(1000-x)
0.5x-6=0.75x
(0.5+x)+x=9.8÷2
(0.5+x)+x=9.8÷2
(x+x)+(x-x)+(x*x)+(x÷x)=81
(0.5x+1)+(0.25x+0.5)+(0.125x+2.25)=x怎么解,
解方程(2.25+3x)³/[(0.5-2x)²(0.25-x)]=(0.75)³/[(0.5)²(0.25)]
(1) 0.2X+0.2*4.8=11.2(2) X/0.5-2.25=0.75(3)5*(X+2)-78=2
2x-0.5[x-0.5(x-1)]=3÷2(x-1)~（>_
