Answer:

15/19

Explanation:

6/x +2/5 = 8

(multiply through by x)

6 + 2x/5 = 8x

(minus 8x from both sides)

-38x/5 + 6 = 0

(subtract 6 from both sides)

-38x/5 = -6

(times by -1)

38x/5 = 6

Times 6 by 5 and then divide by 38.

=15/19

Answer:-


\pink{\bigstar} Value of x
\large\leadsto\boxed{\tt\purple{(15)/(19)}}

Given:-


  • \sf (6)/(x) + (2)/(5) = 8

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:-

  • Value of x.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf (6)/(x) = 8 - (2)/(5)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Taking L.C.M:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf (6)/(x) = (40-2)/(5)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf (6)/(x) = (38)/(5)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Cross multiplying:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf 6 * 5 = 38 * x

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf 30 = 38 * x

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Taking x term one side:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf x = (30)/(38)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Simplifying the fraction:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\large{\bold\red{x = (15)/(19)}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, value of x is 15/19.
