\(\frac{-1}{4}-\frac{3}{4}:x=\frac{-11}{36}\)
\(\frac{3}{4}:x=\frac{-1}{4}-\frac{-11}{36}\)
\(\frac{3}{4}:x=\frac{1}{18}\)
\(x=\frac{3}{4}:\frac{1}{18}\)
\(x=13,5\)

Ai ngang qua xin để lại 1 L - I - K - E

Bài 1:
a: \(x=\dfrac{2}{3}:\dfrac{3}{5}=\dfrac{2}{3}\cdot\dfrac{5}{3}=\dfrac{10}{9}\)
b: \(x=\dfrac{17}{8}:\dfrac{7}{17}=\dfrac{17}{8}\cdot\dfrac{17}{7}=\dfrac{289}{56}\)
c: \(x=-\dfrac{3}{4}:\dfrac{7}{12}=\dfrac{-3}{4}\cdot\dfrac{12}{7}=\dfrac{-63}{28}=-\dfrac{9}{4}\)
d: \(\Leftrightarrow x\cdot\dfrac{1}{6}=\dfrac{3}{8}-\dfrac{1}{4}=\dfrac{1}{4}\)
hay \(x=\dfrac{1}{4}:\dfrac{1}{6}=\dfrac{3}{2}\)
e: \(\Leftrightarrow\dfrac{1}{2}:x=-4-\dfrac{1}{3}=-\dfrac{17}{3}\)
hay \(x=-\dfrac{1}{2}:\dfrac{17}{3}=\dfrac{-3}{34}\)

\(\Rightarrow\frac{3}{4}:x=-\frac{1}{4}-\left(-\frac{11}{36}\right)=\frac{1}{18}\Rightarrow x=\frac{3}{4}:\frac{1}{18}=\frac{27}{2}\)
\(\frac{3}{4}:x=\frac{-1}{4}+\frac{11}{36}\)
\(\frac{3}{4}:x=\frac{-9}{36}+\frac{11}{36}\)
\(\frac{3}{4}:x=\frac{1}{18}\)
\(x=\frac{3}{4}:\frac{1}{18}=\frac{3}{4}.\frac{18}{1}=\frac{27}{2}\)

2x - 36 = 46 : 43
2x - 36 = 64
2x = 64 + 36
2x = 100
x = 100 : 2
x = 50
5x+ 11= 36
5x = 36 - 11
5x = 25
=> x = 2
k mik nha làm ơn
a)\(2x-36=4^6:4^3\Rightarrow2x-36=4^3\Rightarrow2x-36=64\Rightarrow2x=64+36\Rightarrow2x=100\Rightarrow x=50\)
b)\(5^x+11=36\Rightarrow5^x=36-11\Rightarrow5^x=25\Rightarrow x=2\)

a. 37-7.(x+1)=40-8.3
37 - 7(x+1) = 16
7(x+1) = 21
x+1 = 3
x=2
b. (x+5).3=11=10+(3+4).4
(sao có 2 dấu bằng, dấu nào là dấu cộng do viết nhầm ???)
c. 25-5.3+4.10=100-5.x
50 = 100 - 5x
5x = 50
x=10
d. 36+2.(x-7)=12+8.(3+5)-36
36 + 2(x-7) = 40
2(x-7) = 4
x-7 =2
x=9
e. 3.(x+7)-9=11.5-5-8
3(x+7) - 9 = 42
3(x+7) = 51
x+7 = 17
x=10

(3x+4):12+17=19
=>3x+4:12=19-17
=>(3x+4):12=2
=>3x+4=2x12
=>3x+4=24
=>3x=24-4
=>3x=20
=>x=20/3
tíc mình nha

a: \(\Leftrightarrow\left(\dfrac{13}{4}:x\right)\cdot\left(-\dfrac{5}{4}\right)=\dfrac{-10}{6}-\dfrac{5}{6}=\dfrac{-15}{6}=\dfrac{-5}{2}\)
\(\Leftrightarrow\dfrac{13}{4}:x=\dfrac{5}{2}\cdot\dfrac{5}{4}=\dfrac{25}{8}\)
hay \(x=\dfrac{13}{4}:\dfrac{25}{8}=\dfrac{13}{4}\cdot\dfrac{8}{25}=\dfrac{26}{25}\)
b: \(\Leftrightarrow\dfrac{3}{4}:x=\dfrac{11}{36}-\dfrac{1}{4}=\dfrac{2}{36}=\dfrac{1}{18}\)
=>\(x=\dfrac{3}{4}:\dfrac{1}{18}=\dfrac{54}{4}=\dfrac{27}{2}\)
c: \(\Leftrightarrow\left(-\dfrac{6}{5}+x\right):\left(-3.6\right)=-\dfrac{7}{4}+\dfrac{1}{4}\cdot8=\dfrac{1}{4}\)
=>x-6/5=-9/10
=>x=3/10
=>3/4:x=-5/9
hay x=-27/20
-1/4 - 3/4:x =11/36
3/4:x = (-1/4) - 11/36
3/4 :x = -5/9
x = 3/4 : (-5/9)
x = -27/20
vậy x =....
