Question

a) 8/x + 1/5 = 2/5 +1/3

giup mik vs

Answer 1

`8/x +1/5=2/5+1/3`

`8/x+1/5=6/15+5/15`

`8/x +1/5=11/15`

`8/x=11/15-1/5`

`8/x = 11/15 -  3/15`

`8/x=8/15`

`=> x=8:8/15`

`x=8 xx 15/8`

`=> x=15`

Answer 2

\(\dfrac{8}{x}+\dfrac{1}{5}=\dfrac{2}{5}+\dfrac{1}{3}\)

\(\Leftrightarrow\dfrac{8}{x}+\dfrac{1}{5}=\dfrac{11}{15}\)

\(\Leftrightarrow\dfrac{8}{x}=\dfrac{11}{15}-\dfrac{1}{5}\)

\(\Leftrightarrow\dfrac{8}{x}=\dfrac{8}{15}\)

\(\Leftrightarrow x=15\)

Answer 3

A) Đề Bài 
--> \(\dfrac{8}{x}+\dfrac{1}{5}=\dfrac{11}{15}\)
--->\(\dfrac{8}{x}=\dfrac{11}{15}-\dfrac{1}{5}\)
---->\(\dfrac{8}{x}=\dfrac{8}{15}\)
----> 8 = \(\dfrac{8x}{15}\)
----> 8 x 15 = 8x 
----> 120 = 8x
---> \(\dfrac{120}{8}=x\)
----> 15=x
--- x=15

Answer 4

`8/x + 1/5 = 11/15`

`-> 8/x = 11/15 - 1/5`

`-> 8/x=8/15`

`-> x = 15`
