Tìm x: x : 7 11 = 22
Câu 2: Tìm x biết:
a)2/9 + x = 1 b) x : 7/11= 22
a x = 1 - 2/9
x = 7/9
b x = 22 x 7/11
x = 14
a, \(\Leftrightarrow x=1-\dfrac{2}{9}=\dfrac{7}{9}\)
b, \(\Leftrightarrow x=\dfrac{22.7}{11}=2.7=14\)
Câu 2: Tìm x biết:
a)2/9 + x = 1
=1-2/9
=9/9-2/9
=>7/9
b) x : 7/11= 22
=22*7/11
=14
tìm x biết
x-7-(11-3x)=22
x-7-(11-3x)=22
x-7-11+3x=22
x+3x=22+7+11
4x=40
x=40:4=10
Vậy x cần tìm là 10
\(x-7-(11-3x)=22\)
\(x-7-11+3x=22\)
\((x+3x)-7-11=22\)
\(4x-7=22+11\)
\(4x-7=33\)
\(4x=33+7\)
\(4x=40\)
\(x=40:4\)
\(x=10\)
Vậy x=10

câu 7 tìm X
c) 22/15/(11-x)+2/3==7/5
đấylà số phân số nha
\(\dfrac{\dfrac{22}{15}}{11-x}\) + \(\dfrac{2}{3}\) = \(\dfrac{7}{5}\)
\(\dfrac{\dfrac{22}{15}}{11-x}\) = \(\dfrac{7}{5}\) - \(\dfrac{2}{3}\)
\(\dfrac{\dfrac{22}{15}}{11-x}\) = \(\dfrac{11}{15}\)
11 - \(x\) = \(\dfrac{22}{15}\) : \(\dfrac{11}{15}\)
11 - \(x\) = 2
\(x\) = 11 - 2
\(x\) = 9
Tìm x, biết
93/17 : x + -4/17 : x + 22/7 : 52/3 = 4/11
Tìm số nguyên xx biết:
(-11)^2.x = (-198) +(-7).(-22).x
tìm x
0,125+7/5.(x-1/8)
(23/5/24 - 22/2/15):(11/5/3 - 10/11/20)
Tìm X
a. 26 - 3 x X = 11
b. 7 x X - X : 1/5 = 28
c. 16 - X + 14 = 22
Giải luôn nhé:
7x - x : 1/5 = 28
=> 7x - x.5 = 28
=> 2x = 28
=> x = 14
c) 16 - x + 14 = 22
16 - x = 36
x = -20
a. 26 - 3 x X = 11
3xX=26-11
3xX=15
X=15:3
X=5
tìm X
22/7 : (11 - X ) + 2/3 = 7/5
mong các bạn giúp mik
\(\frac{22}{7}:\left(11-x\right)+\frac{2}{3}=\frac{7}{5}\)
\(\frac{22}{7}:\left(11-x\right)=\frac{11}{15}\)
\(11-x=\frac{30}{7}\)
\(x=\frac{47}{7}\)
Vậy \(x=\frac{47}{7}\)
\(\frac{22}{7}\div\left(11-x\right)+\frac{2}{3}=\frac{7}{5}\)
\(\Leftrightarrow\frac{2}{7}-\frac{22}{7x}+\frac{2}{3}=\frac{7}{5}\)
\(\Rightarrow\frac{30x}{105x}+\frac{330}{105x}+\frac{70x}{105x}=\frac{147}{105x}\)
\(\Rightarrow100x+330=147\)
\(\Rightarrow100x=-153\)
\(\Rightarrow x=-1,53\)
#)Giải :
22/7 : ( 11 - X ) + 2/3 = 7/5
22/7 : ( 11 - X ) = 7/5 - 2/3
22/7 : ( 11 - X ) = 11/15
11 - X = 22/7 : 11/15
11 - X = 30/7
X = 11 - 30/7
X = 47/7

tìm x
a).2/7 nhân x=2/3
b).2/5:x=1/3
c).x:7/11=22
lafm đầy đủ tick
a)2/7*x=2/3
x=2/3:2/7
x=7/2
b)2/5:x=1/3
x=2/5:1/3
x=6/5
c)x:7/11=22
x=7/11x22
x=14
mình trả lời xong rồi
tích đúng cho mình nha
Tìm số nguyên x biết:
1)30/7* 34/15 ≤ x < 6/5/16 + 2/11/16
2)-15/5 ≤ x< 22/11
3)19/2*x - (1,73x+3,27x)+7/4 = 4,9
