X^3-7X^2+18X-24=0
24:x=36:18,x=?
(x-22)+(x-24)+(x-27)+(x-20)=x
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
问18x+37=51.4 x=?9x-7x=50 x=?5x+6x=16.94 x=?12x/4=24 x=?
14X-8X=12 20X-50=50 28+6X=88 24-3X=3 99X=100-X X+3=18 X-6=12
x^2=(x+30)X(x-18)怎么解
x+(x+24)+(x+4)/2=7x
x(x-1)=18
x-0.7x=18
X+5X=18
3x-x=24
