(0.25X+16)/(0.75x-16)=9/11怎么解
(0.25X+16)/(0.75x-16)=9/11怎么解
(0.25X+16)/(0.75x-16)=9/11怎么解
化成分数
(1/4X+16)/(3/4X-16)=9/11
(1/4X+16)*11=(3/4X-16)*9
(X+64)*11=(3X-64)*9
16X=640
X=40
请将X-16=0.75X+16-2 0.25X=30 X=120
16x*x+24x*x+9
x^-16/(x^+8x+16) +x/(x-4)
16+0.2x=0.25x十9求x!
x+x(x*16)=9000 x+x(x*15)=8000 求这两题X解
X-0.36X=16,求X
x-0.8x=16 x=?
16-x^/x^+x-20 约分
0.25x+0.4x+0.25x+16=x 这个方程怎么解,
(x+3)(x+7)(x-3)(x-7)+16化简
x^2-8x+16分之x^2-4x
5-x/x-3/(x+3-16/x+3)化简
(x^2 + 4x)(x^2 + 4x+8)+16
(x-2)(x+2)(x^4+4x^2+16)
(x^2-4x)/x^2-8x+16
(x^2-4x)(x^2-4x+8)+16
化简16x-x的三次方 /x^+x-20
