Question

Tìm X:

Answer 1

\(\dfrac{2}{3}\)\(x=\) \(\dfrac{7}{12}\) \(-\)\(\dfrac{1}{4}\)

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

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

\(x=\)\(\dfrac{3}{6}\)\(=\)\(\dfrac{1}{2}\)

Answer 2

\(\dfrac{7}{9}x=\dfrac{5}{36}+\dfrac{9}{12}\)

\(\dfrac{7}{9}x=\dfrac{32}{36}\)

\(x=\)\(\dfrac{32}{36}:\dfrac{7}{9}\)

\(x=\)\(\dfrac{288}{252}\)\(=\)\(\dfrac{72}{63}\) \(=\)\(\dfrac{8}{7}\)

Answer 3

7/9x=5/36+9/1

7/9x=32/36

x=32/36:7/9

x=288/252X

=72/63 

X=8/7

Answer 4

2/3x= 7/12 −1/42/3x=1/3x=1/3 : 2/3x=3/6X=1/2
