Question

Tìm X biết:

X x 1/4 + X x 1/3 =2

Cần gấp ạ!!

Answer 1

`x xx1/4+x xx1/3=2`

`=> x xx (1/4+1/3)=2`

`=> x xx (3/12+4/12)=2`

`=> x xx 7/12=2`

`=> x=2:7/12`

`=>x=2xx12/7`

`=>x=24/7`

Answer 2

X x (1/4 +1/3)=2

X x 7/12=2

x= 2 : 7/12

x=24/7

Answer 3

\(x.\dfrac{1}{4}+x.\dfrac{1}{3}=2\)

\(x.\left(\dfrac{1}{4}+\dfrac{1}{3}\right)=2\)

\(x.\dfrac{7}{12}=2\)

\(x=\dfrac{24}{7}\)
