Question

a) x/12 - 5/6 = 1/12

x/12 = 1/12 + 5/6

x/12=11/12

b)3/2x=1/2+4

3/2x=7/2

x= 7/2:3/2

x=7/3

 

Answer 1

mọi ngừi ơi làm như vậy đúng chưa

Answer 2

\(a)\dfrac{x}{12}-\dfrac{5}{6}=\dfrac{1}{12}\) 

\(\dfrac{x}{12}=\dfrac{1}{12}+\dfrac{5}{6}\) 

\(\dfrac{x}{12}=\dfrac{11}{12}\) 

vậy \(x=11\) 

 

Answer 3

\(b)\dfrac{3}{2}x=\dfrac{1}{2}+4\) 

\(\dfrac{3}{2}x=\dfrac{9}{2}\) 

\(x=\dfrac{9}{2}:\dfrac{3}{2}\) 

\(x=\dfrac{18}{6}=3\)
