Question

I already answered this, but I ain't sure ‘bout the answer that I got. So, I need clarifications, can you solve this for me please? ​

Answer 1

`35x( (3)/(7) = (1)/(5) + (1)/(x) ) \\ = > 35x * (3)/(7) = > 35x * (1)/(5) + 35x * (1)/(x) \\ = > 5x * 3 = 7x + 35 \\ = > 15x = 7x + 35 \\ = > 15x - 7x = 35 \\ = > 8x = 35 \\ = > x = (35)/(8) \\ = > x = 4.375`

Answer:

x = 4.375
