- 1/4.x - 1/3 . ( 2 -3/2 . x + 1/2 - 3) = 4
- 1/4 x - 1/3 + 1/2 x - 1/6 + 1 = 4
- 1/4 x + 1/2 x= 4 + 2/3 + 1/6 - 1
( -1/4 + 1/2 ) x = 23/6
1/4 x = 23/6
x = 23/6 : 1/4 = 43/3
- 1/4.x - 1/3 . ( 2 -3/2 . x + 1/2 - 3) = 4
- 1/4 x - 1/3 + 1/2 x - 1/6 + 1 = 4
- 1/4 x + 1/2 x= 4 + 2/3 + 1/6 - 1
( -1/4 + 1/2 ) x = 23/6
1/4 x = 23/6
x = 23/6 : 1/4 = 43/3
Bài 3. Tìm x biết
a, (10/3: x).(-5/4)=-5/3-5/3
b, (-6/5+ x):(-18/5)=-7/4+1/4:1/8
c, -22/15. x +1/3=-3/5+1/5
d,(0,25-30% x).1/3-1/4=-31/6
e, (0,5 x-3/7):1/2=8/7
Thank you very much !
tìm x
a 5×4^x=80
b 15-|x|=25
c x^2-[6^2-(8^2-9×7)^3-7×5]^3-5×3=1^3
d (x-7)^3=2^5×5^2+2×10^2
giúp mình nha tick 5 nè thank you very much
💚💚
tìm x
1)[2.(70-x)+23.32]:2=46
2)6x-39=5628:28
3)2x-138=23.32
4)219-7(x+1)=100
5)14 chia hết (2.x+3)
6)2.(x-8)=22
nhanh lên mình đag gấp mai nộp rùi
nhớ ghi lời giải
Thank you very much!
mà câu 1 đang gấp nhé
please help me.thanks you very much
tìm các số nguyên x và y
a. (x+2)(y-3)=5
b.(x+1)(xy-1)=3
Tìm x, biết:
2.|x+4|-|x-2|+3.|x-5|=13
THANKS VERY MUCH!!!
Tìm X,biết :
x(2x-4) - 2x(x+3) - 3(x-1) - 29 = 0
Làm giúp mik với
tks very much !!!!!!
a,2-|3/4-x|=7/12 b,1/2x+1/8=3/4 c,(2x-4,5)chia3/4-1/3 giup minh voi ai dung minh se tick nha thanhs you very much
Tìm x, biết:
a.1/4+3/4.x=3/2-x
b.3/5.x-1/4=1/10.x-1/2
c.3x-3/5=x-1/4
d.3/2.x-2/5=1/3.x-1/4
Tìm x biết
a,(2-x)-(2.x-5/2)-|-2|=x-1/4
b.2.(x-1/3)-1/3.x=-1/4-x
c,3/2:/-1|3.x+1/3|/=|5/3-2
d,(3/4-2.x)4-2=79
e,(-4)mũ x+3-1=15
tìm x
a) -1/8 = 3/x b) x/3 = 3/x c)3/4 . x = 1 và 1/2
d) x - 3/10 = 7/15 : 3/5 e) -4/7 - x = -8/3 . 3/7
f) 4/7 . x - 2/3 = 1/5 g) 2/3 + 1/3 : 3 x = 1/5
h) 2/9 - 7/8 x=1/3 j) (2 và 4/5 x - 50) : 2/3 = 51
