﹚(12+x﹚÷2=7 9×﹙x﹢6﹚=2x﹙14+11x﹚ 168-5x=9x .x+4=40-x-8 7×﹙x-2﹚=2x+36×﹙2x-7﹚=5×﹙x﹢8﹚+2 4.5-0.36x=6-0.51x 1500x=1200×﹙9-x﹚x÷5+9=21 30÷x+25=85 会做哪道就做哪道吧!
5.2-0.36x=70-0.51x
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
6x=4.5x(84-x)何解?
4.5×4-2x-2x=6x
6x+0.4x-0.2x=4.5
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
x-0.36x=1.6 x=?
X-0.36X=16,求X
int x=6; x += x -= x * x; printf(x = %d
,x);
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
2x+3x+4x+5x+x+6x+7x=100
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,=x^2/x(x-2)+(2x-4)/x(x^2-4)-(x^2+6x)/x(x^2-4)=x^2/x(x-2)-(x+2)/x(x-2)=(x-2)(x+1)/x(x-2)=(x+1)/x
