X-(7/16-5/24)=7/24
2x=(5x-24)*7/16 2/5x=(x-24)*7/16
5x/24 -2=(-x)+7 /16
X+X/7=(X-24)+[(X-24)/5] 这个方程怎么解
7x-24=x^2+5x
x+(x+24)+(x+4)/2=7x
4x+7x=150-7 19x-5(3x-4)=24 2(4x-3)+(15-2x)=24+12
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
x+(x+24)+(x+24)/2=7x
解方程:6x(7-x)=36-2x(3x-5) (x+6)(x-5)-(x-1)(x+4)=-24
4X-24=2X+20 2X(X-0.7)=4.8 0.6X+3X2.5=67.5 (X-7)除以3=8 5X-1.5X
(x+24)+x+(x/2+12)=7x 怎么解
