Question

tìm x bt
1/3x-3/4=5/4

Answer 1

\(\dfrac{1}{3}x-\dfrac{3}{4}=\dfrac{5}{4}\\ \dfrac{1}{3}x=\dfrac{5}{4}+\dfrac{3}{4}\\ \dfrac{1}{3}x=2\\ x=2:\dfrac{1}{3}\\ x=6\)

Answer 2

1/3x-3/4=5/4

1/3x       =5/4+3/4

1/3x        =2

     x       =2:1/3

     x       =6

 

Answer 3

\(1/3x=5/4+3/4=>1/3x=8/4=>x=2:1/3=2*3=>x=6\)

Answer 4

\(\dfrac{1}{3}x-\dfrac{3}{4}=\dfrac{5}{4}\)

\(\dfrac{1}{3}x = \dfrac{3}{4} + \dfrac{5}{4}\)

\(\dfrac{1}{3}x = \dfrac{8}{4}\)

\(\dfrac{1}{3}x = 2\)

\(x = 2 : \dfrac{1}{3}\)

\(x = 6\)

\(\text{ Vậy x = 6 }\)

Answer 5

1/3x-3/4=5/4

1/3x       =5/4+3/4

1/3x        =2

     x       =2:1/3

     x       =6

 

Answer 6

1 3 x − 3 4 = 5 4 1 3 x = 5 4 + 3 4 1 3 x = 2 x = 2 : 1 3 x = 6

Answer 7

\(\dfrac{1}{3}x-\dfrac{3}{4}=\dfrac{5}{4}\)

\(\dfrac{1}{3}x=\dfrac{5}{4}+\dfrac{3}{4}\)

\(\dfrac{1}{3}x=2\)

\(x=2\div\dfrac{1}{3}\)

\(x=6\)
