\(-1-x=\dfrac{14}{3}\\ 1+x=\dfrac{14}{3}\\ x=-\dfrac{14}{3}-1\\ x=-\dfrac{17}{3}\)
`-1-x=14/3`
`=>x=-1-14/3`
`=>x=-3/3-14/3`
`=>x=-17/3`
Vậy `x=-17/3`
=> x = -1 - \(\dfrac{14}{3}\)
=> x = \(\dfrac{-17}{3}\)
\(-1-x=\dfrac{14}{3}\\ 1+x=\dfrac{14}{3}\\ x=-\dfrac{14}{3}-1\\ x=-\dfrac{17}{3}\)
`-1-x=14/3`
`=>x=-1-14/3`
`=>x=-3/3-14/3`
`=>x=-17/3`
Vậy `x=-17/3`
=> x = -1 - \(\dfrac{14}{3}\)
=> x = \(\dfrac{-17}{3}\)
TÌM X:
(x+1) :(3/1*2+3/2*3+3/3*4+.........+3/14*15)=1và 1/14
Tìm x: Cần gấp ạ
1, -15 + x= - 14 - (-57) 2,(-14) + x - 7 = -10 3, -x - 14 + 32 = -26 4, x-(-19) - (-11) = 0
x + (x+1) + (x+2) + (x+3) + .... + 13 + 14 = 14
25 + 24 + 23 +...+ x + (x - 2) + (x – 3) = 25
Tìm x
a) -x/27 -1 = 2/3
b) x - 4 = -14/35 : 20/-21
c) x + 2/3 = -1/12 . -4/5
d) 1/5 - 3/5x = -15/14 :20/-21
e) -3/7x = 3/5 . 28/9
f)1/2x + 3/5x = -2/3
a)x+3/5=-1/15
b) x/14=1/7-3/14
C)-1/2x+1/5=3/10
d) 4/5-(2/15+x)=1/15
1. Tìm x : 1/2 + 1/14 + 1/35 +....+ 1/x(x+3):2 = 9/14
Mong các bạn giúp mình !
Tìm số nguyên x:
x+(x+1)+(x+2)+(x+3)+....+(x+13)+(x+14)=14
Tìm x, y, z biết
1/ x/14 = -6/y= 60/70
2/ x-2/3= 14/x-3
a, x+30%x=-1,3
b, 1/2-2/3x+1/5=2
c, -3.(x+1/6)-1/2.(2-x)=-1/3
d, 14+x/7=2x+9/14
X/14= 1/7+-3/14
