`x xx 3/4 =11/4`
`=> x=11/4 :3/4`
`=> x=11/4 xx 4/3`
`=> x= 44/12`
`=>x= 11/3`
Vậy `x=11/3`
Lời giải:
$x\times \frac{3}{4}=\frac{11}{4}$
$x=\frac{11}{4}: \frac{3}{4}=\frac{11}{3}$
(x-2)/3 = (x+1)/4
tìm x
e, 2.(1/2.x-1/3)-3/2=1/4
tìm x
Timf `x`:
`(x - 2)/3 = (x + 1)/4`
`(x - 2) . 4 = (x + 1) . 3`
`<=> 4x - 8 = 3x + 3`
`<=> 4x - 3x = 3 + 8`
`<=> (4 - 3)x = 11`
`=> x = 11`
-4/3 - 5/7 + 4/3 3/13 x 6/11 + 3/13 x 9/11 - 3/13 x 4/11
4.(x-3)-(11+x)=58
5x-2+3(x-5)=x
4(x-11)-2(3x)=15-x
Tìm x\(\in\)Z, biết:
a)3-5+(-x+3)=6
b)(-4-x)+(4-15)=-15
c)(11+x)-(-11-9)=32
Tìm x
4.(x-3)-(11+x)=58
5x-2+3(x-5)
4(x-11)-2(3x)=15-x
3/13 x 6/11 + 3/13 x 9/11 - 3/13 x 4/11 = ?
Nhanh giúp mình ạ
Bài 1 Tìm x,biết
x.3/5=2/3
x.7/17=17/8
3/4 chia x=-7/12
3/8 - 1/6.x=1/4
1/3+1/2 chia x=-4
Bài 2 Tính
-6/11 chia [3/5 . 4/11]
7/12 + 5/12 chia 6 -11/36
[4/5 + 1/2] chia [3/13 - 8/13]
[2/3 - 1/4 + 5/11] chia [5/12 + 1 -7/11]
