tìm x biết ( 3/2 - 5/11 - 3/13 ) (2x - 2) = ( -3/4 + 5/22 +3/26)
giải giúp mik vs ạ
mik đang cần gấp cảm ơn trc ạ
(3/2-5/11-3/13)+(3/-4+5/22+3/26)
Ai làm nhanh mik tick nhé!
{(-5/7)-7/9+9/11-11/13}x(3-3/4)
(10/21+14/27-6/11+22/39):(2-2/3)
Bài 1:
a.35 1/6:(-4)/5-46 1/6:(-4)/5
b.1/6+5/6.3/2-3/2+1
c.-1/12-(2 5/8-1/3)
d.-5/4.8/9+-7/16.8/9-2
e.1/6.(-2 3/5)+1 2/5.(-13/5)
Bài 2
a.-5/8+x=(-2/3)^2
b.-1/4-3/4:x=-11/36
c.-22/15x+1/3=/-2/3-1/5/
d./-1/2-x/=1/3
e./2x+3/4/-6=-5
f.-5/7-/1/2-x/=-11/4
g.//x+5/-4/=3
h./17x-5/=/17x+5/
i./x-1/=2x-5
k.(x-1)^3=27
l.(2x-1)^2=25
n.5^x+2=625
m.(2x-1)^3=-8
o.x^2+x=0
tìm số hữu tỉ x trong tỉ lệ thức:
a, 0,2:6/5=2/3:(6x+7)
b,(13+1/3);4/3=26:(2x-1)
c,37-x/x+13=3/7
Bài 1: thực hiện phép tính
a, (3/8 + -3/4 + 7/12) : 5/6 + 1/2
b, -7/3. 5/9+ 4/9. (-3/7)+ 17/7
c,117/13 - (2/5 + 57/13)
d, 2/3 - 0,25 : 3/4 + 5/8 .4
Bài 2: tìm x biết
a, 2/3 x - 1/2 = 1/10
b, -2/3 -1/3 (2x -5) = 3/2
c, (3x -1) (-1/2 x + 7) =0
d, 17/2 - | 2x - 3/4 | =-7/4
e, (x + 1/25) +17/25 = 26/25
tìm x biết
1) x=-1/2 + 3/4 2) x - 1/5 = 2/11 3) x - 5/6 = 16/42 + -8/56
4) x/5 = 5/6 + -19/30 5) |x| - 1/4 = 6/18 6)x = -1/2 +3/4
7) x/15 = 3/5 + -2/3 8)11/8 + 13/6 = 85/x 9) x - 7/8 = 13/12
10) x - -6/15 = 4/27 11) -\(\dfrac{-6}{12}\)+ x = 9/48 12) x - 4/6 = 5/25 + -7/15
Tìm x, biết :
1) x+1 / x-2 = 3/4
2) 2x - 3 / x+1 = 4/7
3) 2x + 3 / 7 = 4x-1/15
4) 11x - 2 / 7x + 5 = 11/8
5) 12 - 7x / -13 = 4 - 3x / -5
tìm x
a, 11/13 -( 5/42 - x) = - (15/28 - 11/13)
b, x +1/3 = 2/5-(-1/3)
c, 2/3 x +5/7 =3/10
d, 3/7-x = 1/4 - (-3/5)
e, -21/13 x + 1/3 = -2/3
