Tìm x biết
X+1/105 + x+3/103 +x+9/97+x+21/85=-4
\(\dfrac{0,\left(3\right)+0,\left(384615\right)+\dfrac{3}{13}x}{0.0\left(3\right)+13}\dfrac{50}{85}\) tìm x
tìm x biết
\(\frac{315-x}{101}+\frac{313-x}{103}+\frac{311-x}{105}+\frac{309-x}{107}+4=0\)
Tìm x
\(\frac{315-x}{101}+\frac{313-x}{103}+\frac{311-x}{105}+\frac{309-x}{107}+4=0\)
a)Tim x biet \(\frac{315-x}{101}+\frac{313-x}{103}+\frac{311-x}{105}+\frac{309-x}{107}+x\)=0
b) Tìm a,b thuộc Z biết (2a + 5b +1) . 2|3a +b| = 105
Tìm x thuộc Q biết:
\(\frac{315-x}{101}+\frac{313-x}{103}+\frac{311-x}{105}+\frac{309-x}{107}+4=0\)
giúp mình nha!
Tìm x, biết:
Ai nhanh nhất mk tick cho
Tìm x,y,z biết:
a) x(x+y+z)=45 ; y(x+y+z)= 75 ; z(x+y+z)=105
b) 1+3y/12 = 1+5y / 5x = 1+7y / 4x
Tìm x
(3x-2).(2x+3)-(6x2-85)-99=0
