1-2x-5/6=3-x/4求x1-2x-5/6=3-x/4求x1-2x-5/6=3-x/4求x1-2x-5/6=3-x/41/4X-2X=3-1+5/6-2X+X/4=3-1/6-7/4X=17/6
1-2x-5/6=3-x/4 求x
1-2x-5/6=3-x/4 求x
1-2x-5/6=3-x/4 求x
1-2x-5/6=3-x/4
1/4X-2X=3-1+5/6
-2X+X/4 =3-1/6
-7/4X =17/6
X = -34/21
解:1-2x-5/6=3-x/4
1/6-2X =3-x/4
-2X+X/4 =3-1/6
-7/4X =17/6
X = -34/21
行不行呢？
移向得，
-7/4x=17/6
所以，x=(17/6)/(-7/4)=-34/21
-1/3
-7/4X=17/6
x= -34/21
(x-1)(x-2)(x-3)(x-4)=(x+5)(x+6)(x+7)求X等于几?
如果1+x+x^2+x^3=0,求x+x^2+X^3+x^4+x^5+x^6+x^7+x^8的值,
已知x=2π+1求 |x-1|+|x-2|+|x-3|+|x-4|+|x-5|+|x-6|+|x-7|+|x-8|+|x-9|+|x-10|
已知x=2π+1.求(X-1)+(X-2)+(X-3)+(X-4)+(X-5)+(X-6)+(X-7)+(X-8)+(X-9)+(X-10)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
